Pogba is making a move on deadline day.

Don’t worry though Manchester United fans, it’s Paul’s brother Florentin.

He’s left Saint Etienne in France to join Genclerbirligi in Turkey.

Watford have just released a statement on Didier Ndong.

They've confirmed they have signed the 23-year-old on loan until the end of the season, with a view to making it permanent in the summer.

Sunderland paid a club record fee for the midfielder in August 2016.

Watford have signed Didier Ndong from Sunderland. On loan with a view to a permanent deal.

What was Matt Rowson just saying about Watford?

INCOMING!

Hey Matt (5:16pm), all is not lost on the chant front...

Watford

The last few months have seen us take five points from 12 games; our blistering start to the season withered in the wake of injuries and persistence with a high energy game that our players' legs and brittle confidence couldn't sustain.

The dismissal of head coach Marco Silva, whose fluttering eyelashes Goodison-wards shattered our illusions of true love, was as inevitable and appropriate as it was disappointing.

Mercifully, we've signed a mercurial winger from Barcelona and all is again right with the world. The arrival of both Gerard Deulofeu and Belgian Dodi Lukebakio firmly ticks the "options on the wings" box, where Richarlíson and Andre Carrillo have had little respite.

We will surely bring in a defensive midfielder on Wednesday, with Didier Ndong seemingly the fallback option if a move for Anderlecht's Dendoncker doesn't come off. Elsewhere a striker was expected, the more so should Stefano Okaka return to Fulham on loan, and options at full back would be welcome.

Pierre-Emerick Aubameyang will wear number 14 for Arsenal.

The new Henry?

If you're just joining us, here's what's gone down on transfer deadline day so far.

Don't forget, there's still five hours and 30 minutes to go until the slam of the proverbial window.

• Arsenal have signed Gabon striker Pierre-Emerick Aubameyang from Borussia Dortmund for a club record £56m.
• Dortmund have confirmed a deal to sign Chelsea forward Michy Batshuayi until the end of the season.
• Meanwhile, Chelsea have signed Arsenal striker Olivier Giroud on an 18-month deal for about £18m.
• Manchester City have ended their interest in Leicester's Riyad Mahrez, after the Foxes priced the deal at £95m.
• Arsenal have confirmed Mesut Ozil has signed a new contract.

Finding out that your favourite player has left the club...

A nice Twitter message from Arsenal to Olivier Giroud, who has joined Chelsea for £18m.

"For the scorpion kicks, the bullet headers, the late strikes, the north London derby winner, the FA Cup final assists, the 105 goals, the 253 appearances and for all the hard work and dedication, we want to say… THANK YOU, OLIVIER GIROUD."

The Mirror were reporting earlier that Riyad Mahrez had gone AWOL again, like he did in the summer when he was apparently hanging around waiting for a deal in an airport in Paris.

If we have any readers at Manchester Piccadilly this evening, keep an eye out for a man with striking blond locks and sadness in his eyes.

Chris Baldwin: oh to be a fly on the wall in the Leicester changing room at training tomorrow. “I’ll get the teas in then lads...lads...lads?

Abdul Said: Three signings for Arsenal and all three are forward players while they have massive issue at the back and midfield area

Matt Stiff: Arsenal losing chant friendly, thrifty Alexis Sanchez and Giroud while gaining the unwieldy Mkhitaryan and Aubameyang. Thoughts with the songs writers at this tricky time

That is considerably poor chant-planning from Arsenal.

Manchester City have walked away from a proposed deal for Leicester City's Riyad Mahrez after refusing to sanction a transfer package that would have cost £95m.

City do not view themselves as having made an offer after Leicester City came to them with a proposal that would have also included a player.

Conversations took place to ascertain Leicester's value of Mahraz - a number of which took place.

City had previously made it clear that they were not willing to spend, however the package was made up, more than £60m.

The difference in valuation was so big that there was no chance of agreement being reached, leaving City to walk away from the deal.

City were not interested in Mahrez simply because Leroy Sane was ruled out for seven weeks with the injury sustained in Sunday's FA Cup win at Cardiff City.

The club had a long-standing desire to bring in an attacking player next summer. They were obviously interested in Alexis Sanchez before he went to Manchester United but felt that was too expensive and have now reached the same conclusion with Mahrez.

With all the commotion of the triangle of transfers, I forgot to do a massive 17:00 GMT countdown.

Here we go, nine minutes late.

SIX HOURS TO GO KLAXON.

(Ok, five hours and 50 minutes)

We'll bring you more on this shortly.

OK...Now it's time for Mahrez news courtesy of BBC Sport's Simon Stone.
