Barcelona are being linked with Manchester United target Dodo.

The Corinthians defender revealed earlier this week that United have first option on him until he turns 21 in 2013. This came after claims that United's call on the left-sided defender had expired in February.

Real Madrid have been in contact with Corinthians to register their interest this season and Radio Cadena Ser says this morning that Barcelona are also keen.

Corinthians coach Mano Menezes has called up the teenager to his first team squad this season, with Dodo drawing comparisons with Brazilian legend Roberto Carlos.
