With less than a day left in the January transfer window, several clubs have been busy. Here, we take a look at five of the best deals struck so far.
Juan Mata (Chelsea to Manchester United, £37.1million)
Mata could the major signing who sparks a revival at Old Trafford, as one of the Premier League's best players in recent years was effectively shown the door at Chelsea by Jose Mourinho. Mata, 25, has a World Cup and European Championship winners' medal with Spain. Such class doesn't come cheap, of course, but he's worth it.
Luuk De Jong (Borussia Moenchengladbach to Newcastle, loan)
Newcastle have long had eyes on Holland international striker De Jong, who flourished under Steve McClaren at FC Twente - including scoring 32 goals in one season - but whose career stalled after a big-money move to Bundesliga side Borussia Moenchengladbach. He is only 23, and if Alan Pardew can restore his confidence then he could be a very useful acquisition.
Lacina Traore (Monaco to Everton, loan)
The so-called 'gentle giant', all 6ft 8in of him, chose Everton over West Ham after Monaco offered him out on loan. Though the Ivory Coast striker is only 23, he made a name for himself as one of the top strikers in the Russian Premier League with Kuban Krasnodar and then Anzhi Makhachkala. Everton fans will also like the fact he has scored a delightful winner against Liverpool, for Anzhi in the Europa League. Watch the goal below:
Mohamed Salah (Basle to Chelsea, £11million).
This goal-scoring winger tormented Chelsea in the three matches he played against them for Basle, scoring in each game. The Egyptian impressed Jose Mourinho so much he used some of the income from Mata's sale to buy him. Chelsea players have likened his playing style to that of Arjen Robben.
Shane Long (West Brom to Hull, £6.5million)
If you are a club with ambitions of a solid mid-table place in the Premier League, then Shane Long is your go-to man. Hard-working, nimble, and - given the ammunition - a clinical finisher, Hull's move for Long proved the Tigers will spend pretty big to keep a seat at English football's top table.
