Manchester United's plans to sign Sporting Lisbon midfielder William Carvalho this summer could be affected by the surprise sacking of David Moyes last month.

Sport Witness reports how the Premier League champions have shown by far the most interest in acquiring the Portugal international's services, but that was prior to the departure of the former Everton boss, who paid the price for a disastrous debut campaign at Old Trafford.

Carvalho was being lined up as a possible midfield reinforcement with the Red Devils ready to meet the 22-year-old's £37million release clause when the transfer window reopens in June.

However, those plans could be 'drastically altered' according to Portuguese newspaper O Jogo, with the impending arrival of Holland head coach Louis van Gaal potentially compromising Manchester United's alleged agreement with the Primeira Liga outfit.

With Juventus also believed to be monitoring Carvalho's situation closely, the Italian giants could hijack Manchester United's proposed move for the player, strengthening Antonio Conte's chances of luring the defensive midfielder to Turin.

Carvalho has enjoyed an impressive breakthrough campaign at Estadio Jose Alvalade, and is set to be rewarded for his impressive form in Leonardo Jardim's side with a place in Paulo Bento's 23-man squad for the 2014 World Cup this summer.

A transfer is unlikely to be formalised before the Sporting star heads off to Brazil, meaning negotiations will probably be put back until mid-July at the earliest.
