Barcelona are preparing a bid for Chelsea midfielder Juan Mata. The Daily Star says the arrival of Jose Mourinho has put his future in doubt.

Sources in Spain suggest Mourinho has blocked a wage increase which Mata, who is contracted until 2016, may have been entitled to.

Barca look likely to sell Christian Tello and Thiago Alcantara and cash from those two deals could fund a £30m bid for the Spanish international.
