Manchester United and Chelsea are interested in Barcelona's sparkling midfielder Andres Iniesta.

DiarioSport says there's concerns among Barca directors that they could lose 23 year-old Iniesta in the next 12 months due to his relatively affordable £40 million buyout clause.

Real Madrid, Juventus, Manchester United and Chelsea are all following Iniesta closely this season.

United manager Sir Alex Ferguson watched Iniesta in action on Sunday in Barca's 3-0 thumping of Atletico Madrid.
