On the subject of Chelsea's new keeper. If you're having trouble getting your tongue around his name, allow the man himself to help you...

Chelsea went big on Wednesday and signed Athletic Bilbao keeper Kepa Arrizabalaga for £71m - a world record for a goalkeeper.

That is because Chelsea goalkeeper Thibaut Courtois looks set to join Real Madrid - with Croatia midfielder Mateo Kovacic expected to move the other way on loan.

Real Madrid also reportedly want Blues winger Eden Hazard - while Willian says he wants to stay at Chelsea after being linked with a move away.

The Blues are unlikely to let any of them go unless they sign a replacement on Thursday. They have only signed one first-team player since Maurizio Sarri's appointment as manager.

Earlier today, BBC Sport towers was wondering how clubs actually send transfer fees to one another.

If it's a bank transfer, does one chairman phone another and ask for his details? Sort code and account number? Then, rather than making up a hilarious reference, like you do with your mates, does he put the player's name?

Maybe Spurs haven't signed anyone yet because Daniel Levy has lost that little calculator that gets you into your online banking.

But I digress...

Tottenham have retained an interest in Jack Grealish throughout the summer which culminated in a £25m bid for the player earlier this week.

Despite Villa's improved financial position - following the takeover by billionaire businessmen Wes Edens and Nassef Sawiris - which has brought a reluctance to sell, the Tottenham chairman Daniel Levy is notorious for driving a hard bargain.

It is thought that Spurs may return with another offer for the player and if it is North of £30m a deal could well yet be concluded.

However, at present Grealish faces another season in the second tier.

Before Manchester City took us by surprise with the signing of a teenage Aussie winger, we were talk about the lack of activity at Spurs.

Tottenham are the only Premier League club not to sign a single player, despite manager Mauricio Pochettino saying at the end of last season they would need to "take risks" to improve.

The Argentine wants to add to his squad but will he be able to get any deal done in time?

There might be one, mind...

Tim: I was given a day to do some tests for a new job. Had a night out, was absolutely hanging the next morning, completed the tests in an awful state just before the deadline, only for the test deadline to then be extended by a week.

Matt: My family and I went to Barcelona for a long weekend and had bought tickets for Barcelona v Sevilla. We were getting ready for it on the Sunday only to realise it had already been played on the Saturday...

Brian Marwood, the managing director of global football for City Group, said: "In a short period of time, Daniel has developed into one of Australia’s brightest young stars and has demonstrated the drive and raw talent required for success at the highest level.

“This pathway was first forged by Aaron Mooy just two years ago, and we are all delighted to see another Australian-grown talent make this move."

Now, don't expect to see Arzani in a Manchester City shirt too soon.

The club say they are "exploring a development pathway for Arzani, and a further announcement regarding a loan to progress his career will be made in the coming days".

Celtic is one possible destination.

Right then, the Premier League's first deal of the day is done.

Manchester City have signed Australia winger Daniel Arzani from Melbourne City.

Arzani, only 19, was part of Australia's World Cup squad. Manchester City and Melbourne City, remember, are part of the same footballing family.

There is a lot of speculation around this morning linking Tottenham’s Danny Rose with a move to Schalke.

Schalke are not confirming their interest in Rose but have admitted they are looking to sign a left-back.

The German deadline is 31 August so it is not a deal that would have to be concluded today.

David Ornstein

Tottenham made Fulham an offer for Ryan Sessegnon several weeks ago and proposed a deal that would see Danny Rose go the other way - Spurs want to move Rose (and Toby Alderweireld for that matter) out - but couldn’t reach an agreement and Sessegnon now won’t be leaving Craven Cottage this transfer window.

Tottenham Hotspur

For Spurs fans, a summer without a single senior in or out, means it hasn’t really started.

There are ways that can be justified. The strength of the squad, the growth of recent years, the financial reality of the new stadium. But there are squad gaps - central midfield - and opportunities to take advantage of that can’t be ignored.

One way or another this is a deadline day that will go down in Tottenham history.

Helen Davies: I once pulled an all nighter to finish an assignment, went to uni in the morning to hand it in and was greeted by a sign on the door telling us we'd been given an extra week to complete it.

Jimmy: Whilst packing my bags to fly back to London from Dubai.... I discovered that the flight was three days ago.

Countdown on, only nine hours left for business to get done.

Jose to get a defender? Jack Grealish to leave Villa? Spurs to get, well, anyone?

17:00 BST. Set your watch.

Kurt Zouma to Manchester United would be an absolute shocker.

He got relegated with Stoke last season.

Chelsea's Kurt Zouma has emerged as a left-field candidate to become the central defensive signing Jose Mourinho wants at Manchester United.

Harry Maguire, Jerome Boateng, Toby Alderweireld and Yerri Mina have all been mentioned as potential signings in recent days.

Add Kurt Zouma's name to that list.

Jose Mourinho signed Zouma for Chelsea in 2014 and it is now being suggested the Red Devils may make a deadline day move for the Frenchman.

Mourinho is doing a planned press conference at 09:00 BST ahead of United's Premier League opener with Leicester tomorrow.

It will be interesting to hear what he has to say.

Now, I said earlier that our top team of journalists will be digging through all the rumours, hearsay and conjecture to bring you all the deals, possibles and no-chances.

Well, we've already got a humdinger...

Pete Gold: On a four hour flights from Turkey, 10am-2pm UK time. Not sure how I will cope not being able to check the transfers. Hoping to have photos of Bernard, Mina and Gomes in Everton shirts by the time I land.

There is an extra little advantage for the really big European clubs - Real Madrid, Bayern Munich, PSG - they don't have to rush because Premier League clubs are going to be out of the game.

They can wait and do their business next week. They will have far less competition, which will stop prices from getting jacked up.

I don't think the Premier League clubs made the right call in closing the transfer window now. They have made a real problem for themselves.

For the past couple of years, it's been a trendy thing for managers to say that the window should close before the season starts.

The problem is that, once the window closes, big European clubs will make offers for players that chairmen and owners will find difficult to refuse.
