Porto are reportedly determined to flog star midfielder Raul Meireles to the highest bidder, with Manchester United and Chelsea interested in securing his signature.
Meireles, 27, was one of the bright spots of Portugal's World Cup 2010 campaign and is rated as one of the best ball winners in European football. With an eye for goal to boot, the £15 million-rated player has been linked with Real Madrid as well as the Premier League duo.
According to O Bola, Porto have virtually transfer listed the player as they look to cash in on his exploits in South Africa.
United manager Sir Alex Ferguson is understood to see Meireles as a replacement for injury plagued battler Owen Hargreaves, who has suffered yet another set back in his bid to overcome a chronic tendonitis problem in his knees.
