The Blues are top of our list despite recording a profit for the past month, with Manchester United, Paris Saint-Germain and Monaco all featuring after being busy in the market...

Chelsea were the biggest spenders of the January transfer window after splashing out just over €52 million on new players during the past month.

Jose Mourinho sealed deals for Kurt Zouma, Mohamed Salah and Nemanja Matic - with the French defender sent back out on loan to Saint-Etienne - but the Blues in fact recorded a profit for the window thanks to the sales of Kevin De Bruyne and Juan Mata.

The Spaniard's record-breaking arrival at Manchester United puts the reigning English champions second in our list, with David Moyes splashing €44.73m on the 25-year-old as he looks to revitalise his side's ailing campaign. French champions Paris Saint-Germain are some way behind in third, with the sole capture of Yohan Cabaye still enough to place them high on the list.
