Tottenham have completed the signings of Juventus pair Rodrigo Bentancur and Dejan Kulusevski, while Tanguy Ndombele has left to join Lyon and Dele Alli has also exited.
Boss Antonio Conte has been searching for extra options throughout the transfer window and now he has brought two players from the Serie A giants.
Bentancur, who was targeted by Aston Villa during this transfer window, was snared by Spurs late on and he has signed a long-term contract to June 2026 with a fee agreed in the region of £15.8million.
The Uruguayan midfielder had made 26 appearances for the Old Lady this season and started as recently as last Saturday against AC Milan, but he has been allowed to leave.
Kulusevski meanwhile only made five starts in Serie A this season and was regularly used as a substitute.
He has signed an 18-month loan deal worth around £8million with an option to make the transfer permanent.
Tottenham are chasing a return to the Champions League and can be backed at 13/8 to secure a top-four spot.
It is no secret that Conte was desperate for reinforcements and there were even some whispers that his future was in doubt due to a perceived lack of backing from above.
However, particularly in the form of Bentancur, he has been granted his wish.
Midfield has been area where Spurs have struggled for consistency this season, with Pierre-Emile Hojbjerg and Oliver Skipp generally the chosen duo.
Harry Winks has also been an option but Bentancur adds further numbers to an important position in the Conte system.
Kulusevski can also ease the burden on the likes of Son Heung-min and Harry Kane as Conte searches for more goals.
One player who has made an exit from Spurs on deadline is Tanguy Ndombele, who has returned to his former club Lyon on loan until the end of the season.
The Frenchman was Spurs' record signing in July 2019 under Mauricio Pochettino, costing around £60million but has never truly established himself as a regular first-teamer under successors Jose Mourinho, Nuno Espirito Santo, and Conte.
There is no question that the 25-year-old is an enormously talented player but was always regarded as a luxury which Spurs couldn't afford to have in their side.
His final appearance came against Morecambe in the FA Cup third round earlier this month and the way he trudged off as he was substituted indicated an unhappy relationship between player and manager - as did the very short statement on the club website confirming his departure.
His deal with Lyon is until the end of the season and has a permanent option of £54million.
Another man leaving Spurs is Dele Alli, with Everton securing a deal which could potentially be worth up to £40million.
The attacking midfielder, like Ndombele, has failed to establish himself under Conte and is now set for a much-needed fresh start.
Under Pochettino, when Spurs were in their pomp, Alli seemed to have the world at his feet and he scored 18 Premier League goals in the 2016-17 season.
However, his form gradually waned and with it, he lost his England place.
The move to Everton looks like it could be a good one - during his playing career, new manager Frank Lampard was a master of making late runs into the box to score goals and Alli was at his best when playing a simplified game.
Another deal which has gone through on a hugely busy day in north London is the departure of winger Bryan Gil on loan to Valencia, only six months after joining.
Meanwhile Giovani Lo Celso also moved on to pastures new as Villarreal snapped up the player on loan.
