Manchester United could face a bidding war with Barcelona and Real Madrid for the signing of William Carvalho this summer, the Daily Star suggests.
Reports from the British newspaper claim that the La Liga heavyweights have been tracking the Sporting Lisbon midfielder and could join the Premier League champions in vying for his signature at the end of the season.
21-year-old Carvalho has impressed during a breakout season with Sporting in the Primeira Liga and even made his international bow for Portugal as a substitute during the crucial second-leg of their World Cup playoff tie against Sweden in November.
The powerful midfielder appears to have attracted attention from Manchester United for a while now, with reports yesterday suggesting that staff of manager David Moyes were present during Sporting's insipid draw against Academica on Sunday night, the eighth time the club have watched Carvalho this season.
With further suggestions that Moyes is now considering a move for the player who has a release clause of approximately £37 million at Estádio José Alvalade, it certainly would come as no real surprise given how poorly Manchester United have performed so far during the 2013/14 season.
Barcelona, meanwhile, currently sit second in La Liga, three points adrift of Diego Simeone's Atletico Madrid following Saturday's surprise 3-2 defeat to a resurgent Valencia at the Nou Camp.
While their midfield is not exactly short of star quality, Barcelona are obviously one of Europe's most-prestigious clubs and could offer Carvalho the chance to learn from some of the world's best players and to compete for regular silverware.
Likewise, Real Madrid - who are currently level on points with Gerardo Martino's men but sit in third by virtue of an inferior goal difference - have a number of top-quality midfield players within their current squad but would surely prove an attractive proposition for Carvalho if they were indeed to compete for his signature in the future.
