We already have an update on Wolves' bid for Red Star's Nasser Djiga...

Could a club bidding for a player they have no hope of signing be called a knock-and-run deal?

The clock is ticking as we enter the afternoon of this transfer deadline day.

Completed deals:

Brighton have confirmed the signing of Stefanos Tzimas from Bundesliga 2 side FC Nuremberg - the move is subject to international clearing.

James Ward-Prowse Nottingham Forest loan returned to West Ham from Nottingham Forest after the two clubs came to a mutual agreement to end his season-long loan.

Aston Villa's Kosta Nedeljkovic, 19, has joined RB Leipzig on loan until the end of the season.

What deals could happen?:

The Guardian are reporting that Crystal Palace have rejected a £70m bid for English centre-back Marc Guehi - BBC football news reporter, Alex Howell has confirmed this.

Alex Howell also reports that Crystal Palace have shown interest in Juventus centre-back Tiago Djalowho is currently on loan at Porto.

BBC Sport's football news reporter, Shamoon Hafez reports that Everton are still waiting to to complete the signing of Carlos Alvarez on loan from Flamengo.

Liverpool's, Jayden Danns, 19, could possibly go out on loan to Championship side Sunderland.

Sorry Ben, yes, of course.

Hello to all those just joining us, don't go anywhere - you won't have the time - the transfer window SLAMS SHUT in JUST 11 hours!!!

Wolves have made a bid for Red Star Belgrade defender Nasser Djiga.

The Premier League strugglers want another centre-back having lost out on Kevin Danso to Tottenham, with reports the offer is around £10m.

They had agreed terms with Danso but had two bids rejected by Ligue 1 side Lens.

Burkina Faso international Djiga, 22, could now move to Molineux and join Emmanuel Agbadou as a new centre-back after Agbadou moved from Reims for £16.6m earlier this month.

Fourth bottom Wolves have conceded 52 goals this season, the third worst defence in the league.

Carlos Alcaraz you say?

We'll start coming up with some tennis puns then.

We are still waiting for Everton to complete the signing of midfielder Carlos Alcaraz on loan from Flamengo, with an agreement being reached between the clubs on Friday.

Sources close to the player had told he was scheduled to fly in and have a medical on Merseyside on Sunday, but we have not have official confirmation of the deal going through.

It remains to be seen what business the Toffees do after that. Manager David Moyes has made no secret about wanting to bring players in, especially a striker.

But who is available out there that can come in and do a job immediately for Everton? It feels like we are waiting for one domino to drop somewhere which could trigger moves in the rest of the chain.

Time is ticking though.

Deadline day is building some momentum now. Let's check in at Goodison Park next...

Crystal Palace had shown interest in Juventus centre back Tiago Djalo.

The 24-year-old is currently on loan at Porto and would have required Juventus to recall him and then loan him to Palace.

That would have required a lot of work and at the moment it seems as if Djalo is going to be staying at Porto.

Is this going to be our big story of deadline day - Tottenham's pursuit of Marc Guehi?

Don't underestimate that final sentence from Alex, too.

"For the Eagles to let Guehi go it would take a massive fee and for them to have a replacement lined up."

Spurs will be hoping Palace have someone waiting in the wings.

There are reports from the Athletic and the Guardian that Crystal Palace have rejected a bid in the region of £70m for Marc Guehi.

We have spoken to one source with knowledge of the offer and they acknowledge that Palace have rejected a bid for their captain.

Mid season deals are always hard to do but a deal to take Guehi out of Crystal Palace may be even harder at this point in time.

The Eagles only have three fit centre backs with Chris Richards, Maxence Lacroix and Guehi.

Trevoh Chalobah has been recalled by Chelsea and Chadi Riad has been ruled out for the season with an ACL injury.

Palace play with a back three and Guehi captains the side.

For the Eagles to let Guehi go it would take a massive fee and for them to have a replacement lined up.

Good point Daniel.

Maybe Arsenal are getting unfair criticism then? Which club could really do with a signing today? Even more than the Gunners.

Ruairi McConville, 19, has completed a permanent move to Norwich City, for undisclosed terms from Brighton.

The Northern Ireland international has only featured twice this season for the Seagulls in the EFL and FA Cup.

Brighton technical director, David Weir said: "Ruairi wants to play regular senior football and establish himself.

“The offer from Norwich City is a very good one for the club, as well as giving Ruairi that opportunity, and we wish him the best of luck for the future.”

The window shuts at 23:00 GMT tonight. Just saying...

Thanks Anon. Remember to leave your names on texts if you can. I can't recall an example of Arsenal signing a forward early in a transfer window.

All I can remember is everyone staying up late to watch them sign Andrei Arshavin in 2009, that was a deadline day move.
