The winter transfer window is only 12 days old - yet clubs across the land have wasted little time in making bold moves to improve their squads.
Here Press Association Sport looks at the most eye-catching switches to date.
OSCAR - CHELSEA TO SHANGHAI SIPG
The most stunning deal of the month so far saw Brazilian player Oscar swap west London for Far East riches in a £52million transfer that showed the ambition of the Chinese Super League. Unlike others who have been lured to China, Oscar, at 25, is still very much in his prime and while Antonio Conte's Blues had seen little value in him, he would have had suitors across Europe. Oscar's contract with Chelsea was also up next year and the fee they recouped was therefore staggering.
MORGAN SCHNEIDERLIN - MANCHESTER UNITED TO EVERTON
Another heavyweight cast aside one of their midfielders when United agreed an initial £20million deal with Everton to offload France international Schneiderlin. Jose Mourinho said he was both "sad and happy" that the 27-year-old would be leaving Old Trafford for regular first-team football under his former Southampton manager Ronald Koeman. The Toffees desperately needed reinforcements this month and Schneiderlin will add more steel in their engine room.
GABRIEL JESUS - PALMEIRAS TO MANCHESTER CITY
Okay, so this one was agreed some time ago, but if Jesus can live up to the hype then perhaps this will be seen in future years as this window's outstanding transfer. City have paid £27million for a 19-year-old who scored on his Brazil debut back in September having helped his country to an Olympic title in their homeland one month earlier. From a country with a rich history of attacking players, Jesus arrives in Manchester with a big reputation and could reinvigorate City's season.
WILFRED NDIDI - GENK TO LEICESTER
The champions hope they have finally landed N'Golo Kante's replacement by bringing Ndidi, 20, to the east Midlands for a £15million fee. Leicester's struggles this year can in part be attributed to the loss of Kante - just look at how his current club Chelsea are benefiting from the midfielder's energy - and Claudio Ranieri will hope Ndidi is the man to fill the void. If he is, the Foxes could shoot up the table in the second half of the campaign.
JOEY BARTON - UNATTACHED TO BURNLEY
Twelve months ago Barton was on Burnley's books and about to help the Clarets to a Sky Bet Championship title by inspiring them to a 23-game unbeaten run. He initially turned down the chance to stay on for the Premier League tilt, preferring to join Rangers in Scotland, but an unsuccessful stint left him out of work again and the Clarets were only too happy to bring him back to East Lancashire. If Barton can replicate his Championship form, Burnley will remain well clear of relegation strife.
