Keep your thoughts coming in on Ederson's legacy and the proposed signing of Gianluigi Donnarumma, but there is no doubt what debate has lit the blue touch paper this morning.

Let's take a closer look now at the Alexander Isak and Yoane Wissa signings, as well as the late collapse of Marc Guehi's proposed deadline day switch from Crystal Palace to Liverpool.

The general tone of your arguments is that Isak and Wissa got their moves by behaving badly - removed from the group at Newcastle and Brentford, respectively, as their futures were sorted out.

While Guehi's transfer fell through after he remained professional throughout and continued to turn out for the Eagles during the transfer window.

Of course, it may not be as simple as that...

Let's start with the views of former footballers Joe Hart, Chris Sutton and Michael Owen.

Joe Hart
Former England and Man City goalkeeper on BBC Radio 5 Live Monday Night Club

He [Donnarumma] is capable with his feet, more than capable. I've watched him play under pressure for Italy, I've watched him from 16 years old. There's a man that can hold his nerve. For AC Milan all the way through and then he goes to PSG and helps to win their first Champions League trophy.

I am a big James Trafford fan, I am pleased with how he has done and how he's gone back to City, but why would you not sign Donnarumma? He can win you games, he is absolutely humongous in goal, making top, top saves at the top level.

Ederson’s departure looks set to open the door for Gianluigi Donnarumma to join Manchester City.

City have agreed a £26m deal with Paris St-Germain for the Italy international on a five-year contract, with the option of a further year.

While the move has not yet been officially confirmed, Donnarumma is widely expected to step in as Ederson’s successor between the posts.

The 25-year-old’s exit from PSG comes after manager Luis Enrique expressed a desire for a "different profile" in his goalkeeper, paving the way for Lucas Chevalier to replace him in Paris.

Donnarumma leaves having already established himself as one of Europe’s top goalkeepers during his time at AC Milan and PSG, where he played a major role last season in helping them clinch a first Champions League title.

Will it be a case of 'the king has gone, long live the king' at Manchester City?

It's a landmark day for Manchester City and Ederson.

Where would you place the Brazil stopper among the Premier League's greatest ever goalkeepers?

We know he leads the way in titles and assists, but has Ederson's time at City changed the way we view goalkeepers?

Ederson won a total of 18 pieces of silverware with Manchester City following his arrival from Benfica 2017.

That haul includes six Premier Leagues, two FA Cups, four League Cups, three Community Shields, one Champions League, one Uefa Super Cup and one Fifa Club World Cup.

The Brazilian's six league titles means he is the most decorated goalkeeper in the Premier League era of English football.

Ederson’s time at Manchester City is coming to an end after a glittering spell that began when he joined from Benfica in 2017 for around £35m.

Since arriving at the Etihad, the Brazilian goalkeeper has made 372 appearances, keeping 168 clean sheets.

A key figure in City’s era of dominance, Ederson has been central to their success under Pep Guardiola, revolutionising the role of a modern goalkeeper with his distribution and composure.

Ederson finished his time at City with seven assists in the Premier League - more than any other goalkeeper.

His departure marks the end of a hugely successful chapter for both player and club.

Ederson was a firm fans' favourite at Manchester City and was always happy to take time out to sign autographs.

That was clear at a recent open training session at the City academy campus, when the Brazilian stopper patiently made his way through the hoards of supporters waiting by the pitchside barriers.

He was one of the first players to engage with fans, stopping for endless selfies, and the last to leave.

Manchester City's director of football Hugo Viana also paid tribute to Ederson’s outstanding contribution to the club:

“Ederson has been an incredible servant to Manchester City.

“The fact no goalkeeper has ever won more Premier League titles says everything you need to know about his quality and consistency in a City shirt.

“He has been a huge figure in all our successes over recent years, and his skills and bravery have been crucial in helping City play the beautiful football we have seen.

“He has truly cemented his place in the history of Manchester City, and we all wish him well in the next chapter of his career.

"And he leaves us knowing that he will always be welcomed at this football club.”

Ederson has released a statement via the Manchester City website following his exit from the club:

"Under Pep, we have dominated the Premier League and conquered Europe. It has been amazing.

"I would first of all like to thank him and head of goalkeeping Xabier Mancisidor for making me the best goalkeeper I could be and teaching me so much about the game.

"I must also thank my team-mates. Our desire to win every game we play has been a joy to be a part of and that has made me relish every day on the training field or in the dressing room with every one of you.

"Finally, the fans. Thank you for making me feel at home in a city so far away from where I am from and for supporting me throughout what has been an amazing period for me and my family.

"I arrived in Manchester eight years ago full of hope, but I could not have predicted such a beautiful time together.

"Playing for City has been the most special time of my life and I will always be a fan of this special club.

"I’m going with my wife and children, but I’m leaving a big family here, Cityzens. Once a Blue, always a Blue."

Remember, BBC Sport reported on Monday that Fenerbahce had agreed to sign Ederson from Manchester City for £12.1m.

This just in from Fenerbahce:

"Our club has reached an agreement with Manchester City for the transfer of Brazilian goalkeeper Ederson. The player has been brought to Istanbul to complete the official signing."

More to follow.

While you ponder those hot takes, let's consider the figures behind what was a remarkable transfer window, even for the Premier League's standards.

Clubs in the English top-flight have splashed out more than ever before as spending this summer surpassed £3bn.

A total of £2.73bn had been spent by 31 August, but big-money deadline day deals - headlined by Alexander Isak's move from Newcastle to Liverpool for a British record £125m - pushed the total to £3.087bn.

The spending was significantly more than last summer, when the outlay by top-flight teams was £1.96bn.

The total this year is more than was spent by Bundesliga, La Liga, Ligue 1 and Serie A clubs combined.

We know, it's a lot to take in.

But stick us with as we delve deeper behind all the main talking points.

As ever, we want to hear from you.

The behaviour of Alexander Isak and Yoane Wissa in forcing through their moves has sparked a big debate, compared with the apparent quiet diplomacy of Marc Guehi.

That's a brief summary of Monday's transfer merry-go-round.

Some deals went through so late that they managed to slip under the radar.

For example, Spurs managed to offload forgotten Bryan Gil to Girona in a permanent deal, while Manor Solomon joined Villarreal on loan.

You can catch up on all the deals by clicking on this link, where you will find a full round-up of deadline day's completed transfers.

There were a number of notable departures from the Premier League on deadline day:

• Nicolas Jackson's on-off loan move to Bayern Munich - which looked to have been scuppered after Chelsea's summer signing Liam Delap pulled up with a suspected hamstring injury in Saturday's win over Fulham - was finally completed on Monday after the Blues recalled Spanish forward Marc Guiu from his Sunderland stay.
• England full-back Ben Chilwell also left Stamford Bridge for Strasbourg in a permanent deal, but there were no moves for fellow Chelsea 'bomb squad' members Raheem Sterling and Axel Disasi.
• Arsenal managed to ship out a couple of squad members deemed surplus to requirements, with defender Jakub Kiwor joining Porto on loan and Fabio Vieira heading out to Hamburg, also on loan.
• Antony's inglorious stay at Manchester United finally came to an end with a £21.65m switch to Real Betis, while Denmark striker Rasmus Hojlund joined Italian champions Napoli in a season-long loan.
• West Ham's Italy defender Emerson Palmieri, who can boast the rare achievement of picking up winners medals in the European Championship, Champions League, Europa League and Conference League, left the Premier League for Marseille.
• And Leicester City legend Jamie Vardy joined Serie A side Cremonese as a free agent after leaving the Foxes in the summer.

There are a number of deals that have been agreed but not finalised, most of them at Manchester City.

We are still waiting on official confirmation of Gianluigi Donnarumma's £26m move from Paris St-Germain, with the Italian goalkeeper making the switch to Etihad Stadium on a five-year contract, with the option of a further year.

Meanwhile, City's long-time number one, Brazil's Ederson, has agreed to join Fenerbahce for £12.1m but the transfer window has not yet closed in Turkey so expect that signing to be confirmed before midday.

It has also been reported that veteran midfielder Ilkay Gundogan has agreed a move to Galatasaray, while Swiss defender Manuel Akanji is set for a season-long loan at Inter Milan.

City are still to announce all of those deals and we will bring you an update when they do.

Before getting into it, let's first sum up the deadline day's marquee signings:

• We woke up on Monday morning to news that Liverpool had agreed a British record fee of £125m for Newcastle striker Alexander Isak and that signing was finally confirmed at around 21:30 BST.
• A dramatic day on Merseyside ended with confirmation that Crystal Palace defender Marc Guehi's planned £35m move to the Premier League champions had fallen through.
• The Magpies re-invested some of their Isak bounty in Brentford's striker Yoane Wissa, paying £55m for the DR Congo international, who turns 29 on Wednesday.
• How both Isak and Wissa engineered their moves is a talking point we will return to later this morning.
• Elsewhere, Aston Villa brought in Sweden centre-back Victor Lindelof on a two-year contract, plus Liverpool's highly-rated midfielder Harvey Elliott and Manchester United winger Jadon Sancho on loan deals.
• Fulham paid a club-record £34.6m for Shakhtar Donetsk's Brazilian winger Kevin.
• Young Belgian goalkeeper Senne Lammens was unveiled at Old Trafford in a deal worth £18.1m after United decided not to pursue a move for Villa's World Cup winner Emiliano Martinez.
• And Tottenham's difficult summer window ended on a high note, with the loan signing of Paris St-Germain forward Randal Kolo Muani.
