Chelsea defender Marcos Alonso wants to leave for Barcelona.

Spain international Alonso has been linked with Barca for much of the season.

Sport says there is already an agreement between Barcelona and Alonso to move to the Nou Camp. He will now ask Chelsea to let him leave.

Barca are happy with Alonso's contract terms and are confident he won't warrant a major fee.

However, there could still be problems with Chelsea given teammates Andreas Christensen and Cesar Azpilicueta are also on track to join Barca this summer.
