As the January transfer window heads into the final hours, new Everton boss Frank Lampard made an immediate splash in the market having been appointed as Rafael Benitez's replacement at Goodison Park.
Manchester United midfielder Donny Van De Beek joined on loan for the rest of the season. No option to purchase Van De Beek permanently was included in the deal, which sees wages covered on top of a loan fee.
It is also believed the Toffees have agreed a fee with Tottenham for England midfielder Dele Alli and Everton will not have to pay an initial fee for the 25-year-old, with a substantial fee payable if and when certain conditions are met.
Spurs were having a busy day of it, even with the Alli deal not yet confirmed.
Having announced the departure of their club-record signing Tanguy Ndombele, who rejoined former side Lyon on loan until the end of the season, Tottenham soon revealed two new arrivals from Juventus.
Rodrigo Bentancur signed a four-and-a-half-year deal at the Tottenham Hotspur Stadium, the Uruguay midfielder moving for an initial fee of €19million, with another €6million in potential add-ons.
Sweden winger Dejan Kulusevski followed soon after, joining on an 18-month loan deal with an obligation to make the move permanent for €35million if certain objectives are met, or the option to complete the deal if not.
Bryan Gil, who only arrived at Spurs last summer from Sevilla, made a swift return to LaLiga having signed on loan with Valencia for six months while Giovani Lo Celso joined Villarreal for the remainder of the campaign.
Bottom club Burnley have completed the signing of Netherlands international Wout Weghorst from Wolfsburg for a reported €12million fee.
The 6ft 6in striker has signed a three-and-a-half-year contract and is set to train with his new team-mates on Monday.
"Wout is a player that our scouts have been strong on for some time and we feel that he can add to all that we do at Burnley Football Club," manager Sean Dyche said.
“His signing is a continued show of the club’s and team’s development. We wish Wout well as he earns the right to push our group forwards.”
Weghorst, capped 12 times by Holland, has scored 59 goals in 118 Bundesliga appearances.
Newcastle were also looking to add to their ranks as they battle against the drop.
Matt Targett arrived on loan from Aston Villa for the remainder of the season, Eddie Howe having already recruited Kieran Trippier, Chris Wood, Bruno Guimaraes and Brighton defender Dan Burn.
