Manchester United have reportedly approached Porto regarding the availability of midfielder Joao Moutinho as Sir Alex Ferguson ramps up his search for new recruits.
The 25-year-old was one of the star turns for Paulo Bento's Portugal side as they reached the semi-final of Euro 2012, although Moutinho saw his spot-kick saved in the penalty shootout defeat to Spain.
According to The Times, United manager Ferguson was impressed by Moutinho's performances in Poland and Ukraine, which has led to the Old Trafford club contacting Porto to enquire about the valuation of the Portuguese.
Moutinho joined Porto from Sporting two years ago for a fee of £8 million, but is now valued at closer to £25 million, and this price is reported to be considered excessive by United.
The creative midfielder is one of several players to have been identified as a possible long-term successor to Paul Scholes, who will remain with United for one more season before retiring for a second time.
United have already completed the signing of Shinji Kagawa, a goalscoring attacking midfielder, from Borussia Dortmund, who moved to Old Trafford for almost £18 million.
