Right, that Lucas Perez fee might not be £6.5m. The £6.5m comes from West Ham's elaborate fantasy football-style unveiling and might just be what he costs in the Premier League game.

The actual fee might be nearer £4m.

Seriously, clubs who make those videos should face a points deduction.

What happened to a picture in front of the home end holding a scarf above your head?

Upon arriving at London Stadium, Lucas Perez said: "I’m very happy to be here at such an historic club."

"I’m very excited, as West Ham are giving me the chance to stay in the Premier League and I’m very happy to be part of this new project.

"West Ham have great fans and play in an amazing stadium, so to sign here brings me great joy. I’m very motivated."

Perez joined Arsenal for more than £17m two years ago, but only made two league starts for the Gunners. He did manage a hat-trick against Basel in the Champions League, though.

He spent last season on loan at Deportivo la Coruna.

Forget it being leaked, this one is confirmed with our first elaborate video of the day.

Lucas Perez makes the move from Arsenal to West Ham. According to the video below the fee is £6.5m.

On the subject of Instagram, it looks like Jack Wilshere has leaked Lucas Perez's arrival at West Ham...

Throughout the day, we’re following fans from Spurs, Stoke, Birmingham and Man Utd on out Instagram story.

They’ll be telling us what their teams need to sign along with their deadline day activity (or lack of it).

Martyn Sansom: Trip to New York with the missus, and I bought tickets to Lion King as a surprise. Getting ready to go and couldn't remember the start time. Checked tickets and loudly read out to the missus, 'yeah, 7pm February 18th' - it was March 18th.

Although Kepa conceded 43 goals in 30 league games last season, that was mainly due to the deficiencies of the weak team in front of him.

His greatest assets are lightning-fast reflexes, allowing him to make stunning close-range stops, and calm composure in even the most frenetic of penalty areas.

And although eyebrows have been raised by the huge fee for a player with just two seasons of top flight experience, the consensus in Spain regards Kepa as the country’s best young goalkeeper with a very bright future.

Liverpool and Chelsea took turns breaking the goalkeeper fee record this summer by signing Alisson Becker and Kepa Arrizabalaga respectively. Both arrive highly-rated but, while only time will tell whether Kepa can fill Courtois’ golden gloves, Alisson looks an obvious upgrade for Liverpool.

For fantasy managers, both keepers offer relatively cheap routes into what are expected to be two of the Premier League’s tightest defences but it’s perhaps Alisson’s influence on Liverpool’s defence as a whole that is of most interest. If he helps them to improve on last season’s 17 clean sheets, Allison’s presence will enhance the output of the likes of Virgil van Dijk and Andrew Robertson whose additional potential for attacking returns might see them get the nod as the Liverpool fantasy defenders of choice.

It’s ironic that Kepa Arrizabalaga is heading to Chelsea to replace Real Madrid-bound Thibaut Courtois, because just a few months ago he nearly simplified the goalkeeper merry-go-round by moving to the Bernabeu himself.

In January, Real moved for Kepa by offering to pay his €20 million buy-out clause with Athletic Bilbao, but he rejected that opportunity by signing a new seven-year contract with the Basque club.

He joined Athletic at the age of nine, but after advancing into the senior squad in 2012 his rise was steady rather than spectacular.

Following loan spells with second tier Ponferradina and Real Valladolid, he finally became a starter for Athletic early in the 2016/17 season, quickly establishing himself by showing impressive poise and maturity.

Tom McMahon: As a Chelsea fan, happy about Kovacic, happy about Kepa, gutted we still haven't begun to solve our biggest problem: Morata isn't cutting it, we need a new striker!

On the subject of the Chelsea-Real-Courtois-Kovacic shenanigans, we're expecting Thibaut Courtois to be confirmed and unveiled by the Spanish giants a little later today.

So, just to confirm, that is ANOTHER midfielder to join Chelsea.

It could mean that Tiemoue Bakayoko is on his way out at some point, maybe Danny Drinkwater (remember him?) too.

Ruben Loftus-Cheek will be wondering where he might get a game too.

Upon arriving at Stamford Bridge, Kovacic said: "I am really happy and excited to be here at Chelsea. It is an amazing feeling. I will try to do my best for this club. It is a new league for me, the beginning is always tough but I am sure the coach and my new team-mates will help me and I am looking forward to a great season."

Kovacic signed for Real from Inter Milan in 2015 and has been part of the squad that has won three consecutive Champions League titles.

He played five games in Croatia's run to the World Cup final.

Chelsea are stocked in midfield, but if a player like Kovacic is available, then you have to get him.

Real Madrid didn't want to let Kovacic go permanently, because they want him to come back and replace Luke Modric.

We knew this was coming, but it's still pretty big news.

Chelsea have signed Croatia midfielder Mateo Kovacic on loan from Real Madrid for the rest of the season.

That one is balled up with the Thibaut Courtois to Real business...

Anyway, Jose might not be signing anyone, but his old club have...

It's looking like Harry Maguire will still be a Leicester player come 17:00 BST.

Jose Mourinho looks as happy as a turkey on Christmas Day and by turning down two offers of up to £60m for Maguire the Leicester owners show we don't need to sell.

Do you remember when listening to Jose Mourinho speak was a pleasurable experience? When you might have been entertained? When one his press conferences was must-see?

Now it's like listening to your grandad tell you it was better in his day. He's football's Geoffrey Boycott.
