Barcelona star Leo Messi is backing a move for Chelsea fullback Marcos Alonso.
Barca management are in the market for a new left-back after failing to be convinced by their current options.
Don Balon says Messi wants Alonso to join him at Barcelona.
The fact Alonso can play either at full-back or as a central defender is said to be an attractive proposition for the Catalan club.
And any deal would not be too expensive as a deal could be done for £35m (€40m).
