And after a 19-hour stint this page is bowing out on the Mamadou Sakho signing.
If you've missed anything - check out all the completed deals here.
I think that signing was held up as they had to do post production on the announcement tweet.
For the hashtag alone.
Mamadou Sakho has joined Crystal Palace.
Who knows what has happened to Mamadou Sakho. I'm going to stick this out until 02:00 UK time though.
Luis Suarez has picked up a knee injury while playing for Uruguay tonight - Barcelona have another day to sign players of course...
Danny Drinkwater says: ‘I’m delighted to be a Chelsea player and can’t wait to get started. It has been a long journey to get here but I am very happy and am looking forward to helping the club win more trophies.’
The fee to sign Danny Drinkwater is around £35m, while the move to bring his replacement Adrien Silva to the club will go through on Friday.
Chelsea signed Ngolo Kante for a fee in the region of £30m last summer, and have now paid more than that for Danny Drinkwater.
Who is the happiest set of fans from this deal?
WE HAVE NEWS
As a Newcastle fan I'd like to point out two positives. 1) we've not sold our best player on deadline day. (Arfa, Caroll, Cabaye, Sissoko eg). 2) maybe with the inflated prices Ashley might realise he's out of his depth and sell.
Paris St-Germain have signed Kylian Mbappe on a season-long loan from Monaco, with an option to make the deal permanent for a fee of £165.7m.
Should PSG sign the France international on a permanent deal, his contract will run until June 2022.
Any deal for the 18-year-old is likely to be eclipsed only by the 222m euros (£200m) PSG paid for Neymar.
"I really wanted to be a part of the club's project, which is one of the most ambitious in Europe," said Mbappe.
The teenager scored his first goal for France in their 4-0 win over the Netherlands in World Cup qualifying on Thursday to become his country's youngest goalscorer since 1963.
Brighton & Hove Albion
BBC Sussex reporter Johnny Cantor:
"Albion applied for an extension until 1am, that was granted but Vincent Janssen couldn't be tempted away from Spurs. The Seagulls came close with an agreement for Florin Andone at Deportivo La Coruna but that deal and a bid for Fiorentina's Khouma Babacar also came to nothing.
‘’There will certainly be a sense of frustration with fans and management as the club failed to secure a much needed striker. Despite an extension until 1am, Albion were unable to tempt Janssen to the Amex while sizeable bids for players abroad failed to attract targets earlier in the day. Striker Tomer Hemed does stay despite interest from Reading. Away from the chase for firepower up front the capture of pacy defender Ezequil Schelotto, known as the Greyhound, and the experienced goalkeeper Tim Krul from Newcastle could well prove to be smart additions.’’

Even Barnet have gone home now.
Come on Chelsea/Leicester/Drinkwater/Silva!
A new hour! Clubs like to announce deals on the hour. Fingers crossed...
Thoughts on Burnley's transfer window? Really not sure they have done enough. Strong squad but still some gaps- despite the promising start to the season.
Still with you awaiting Drinkwater anxiously, on Eurotunnel from Calais to Folkestone!
Wilfried Bony. Wearing number two. A low point.
No. No. No.

Just some late Scottish deals you may have missed:Aberdeen have signed Dominic Ball on a season-long loan from Rotherham. That came through right on midnight.Hearts have signed winger Manuel Milinkovic on a season-long loan from Genoa.
An update from the people at Leicester - they are still waiting for news of the Danny Drinkwater/Adrien Silva deal.
Deals, deals, deals. But what are the rules that govern them? The Premier League have given us some guidance on loan deals. Here we go...
These are officially called temporary transfers. Under Premier League rules, there are restrictions on how many players Premier League clubs can loan from other Premier League/English clubs. They are:
You and me both Mark! Let's give them a nudge.
Mark Burgess: Still with you! Waiting for news on Drinkwater
Who's still with me? Anyone?
We were on air on Facebook earlier with Football Gossip Live, analysing what happened to the Alexis Sanchez deal and who was the best piece of business during the window.

I somehow missed this one earlier - check out Wilfried Bony's singing here after he moved back to Swansea...
Barnet have pulled off a bit of a lower-league coup with the signing of Dave Tarpey from Maidenhead.
He turned down a move to Coventry earlier in the summer as he could make more money staying part-time.
The very late announcement of the defensive midfielder Alfred N'Diaye's arrival at Molineux at least prevented Wolves from drawing a blank on deadline day. The 27-year-old Senegalese international has Premier League experience, having spent the second half of last season on loan at Hull and had a previous spell at Sunderland, and will be with Wolves on loan from Villarreal for the season.
A solid signing - but Wolves did not land the striker they so obviously need. Their plans were apparently scuppered by a change of heart from PSV Eindhoven, who were reportedly happy to accept an eight-figure offer for the forward Jurgen Locadia until early evening.
Leo Bonatini is therefore the only specialist senior striker available following the sale of Nouha Dicko on Wednesday, although a number of others in the squad can play in that role too. Taking the window as a whole, Wolves were certainly busy bringing in players, but arguably they failed - for whatever reason - to fill the most important gap. Bonatini has made an encouraging start to his career in England, but he may find he is carrying a heavy burden for a while.
Mamadou Sakho was having a medical with Crystal Palace at about 15:00 BST. What is going on?!
The Liverpool defender may still be on the move...
Chelsea signed defender Davide Zappacosta from Torino on a four-year deal for an undisclosed fee just before the end of the window.
The 25-year-old has been capped four times by Italy, with Blues boss Antonio Conte handing him his first call-up to the national squad in May 2016.
The full-back joined Torino from Atalanta in 2015 and made 29 Serie A appearances last season.
"I hope I can show my quality to the coach, my team-mates and the supporters," said Zappacosta.
Birmingham, you've signed everyone. Stop it.
Everton's claim that Ross Barkley turned down a move to Chelsea after having a medical and agreeing a contract have been disputed by a source close to the England midfielder.
Majority shareholder Farhad Moshiri said Everton had accepted a bid and Barkley had agreed personal terms before changing his mind after passing a medical.
But the source said the 23-year-old did not travel to Chelsea.
And they said he had not had a medical.
"It was simply that he would rather make a decision about his next move when he is fully fit, rather than arrive at a new club injured," the source said.
Oustanding globetrotting work. Former West Ham midfielder Ravel Morrison has joined Mexican side Atlas.
