Sanchez remains at Arsenal but Gunners lose the Ox
Mbappe joins Neymar at PSG
The biggest transfer on deadline day came from Paris St Germain, but it was frustrating for many of the big Premier League clubs after a string of major deals collapsed.
The French Ligue 1 side followed up their world-record signing of Neymar with the capture of Monaco forward Kylian Mbappe, who celebrated hours later by scoring his first international goal in France's 4-0 thrashing of Holland.
The player joins on a season-long loan, but reports suggest PSG are obligated to pay £165m next summer as they seemingly look to skirt around Financial Fair Play requirements.
However the big deals proved harder to complete in England. Alexis Sanchez remains an Arsenal player despite the attempts of Manchester City, but the Gunners failed in a £92m bid to lure Monaco's Thomas Lemar to the Emirates.
Arsenal also lost one of their best young stars, with Alex Oxlade-Chamberlain confirmed as a Liverpool player following a £35m switch.
The England international turned down the offer of a new contract at the Emirates and a late bid from Chelsea. He is set to play for England in Malta and is 4-7 with Betway to make the Three Lions’ squad for next year’s World Cup finals in Russia, while it's 5-6 that he makes 15 starts for Liverpool this season.
But Liverpool failed in their attempt to prise defender Virgil van Dyke away from Southampton. Barcelona target Philippe Coutinho is still with the Reds, although the La Liga window remains open until Friday night.
Divock Origi left Anfield to join Wolfsburg on a season loan and Crystal Palace snapped up Reds defender Mamadou Sakho, but the Eagles failed to complete a deal for Everton outcast Oumar Niasse in time.
Chelsea had problems sealing deals, with Everton's Ross Barkley deciding against move during his medical despite a fee of £35m being agreed. A move for Leicester's Riyad Mahrez also failed to materialise, and Spurs snatched Swansea striker Fernando Llorente from under the Blues' noses rumoured to be a bargain £12m.
Diego Costa remains on Chelsea's books but a deal with Atletico Madrid could still happen on Friday, however the Blues did land Davide Zappacosta from Torino for £23m and Danny Drinkwater from Leicester for £35m.
In addition to Llorente, Spurs bagged right-back Serge Aurier from PSG in a £23m move.
Despite losing Llorente Swansea had a good day, sealing a deal for Renato Sanches from Bayern Munich on a season loan and snapping up former Swans striker Wilfried Bony from Man City for £12m.
