Louis Van Gaal has identified Alexis Sanchez as one of his top targets this summer, but he may have to wait until after the World Cup to sign the winger with Barcelona unwilling to listen to offers until Chile's campaign in Brazil finishes.
However, the 25-year-old's potential arrival in Manchester could have a knock-on-effect for a number of current first team players. Here's a lowdown on the five players that may see their game time reduced if the Chilean completes his move.
The Portugal winger was given a surprising new five-year-deal last summer by then manager David Moyes, but after another underwhelming season, Nani will find it hard to cement a place in the first team under Van Gaal. Since his €25.5 million move from Sporting CP in 2007, he has failed justify his price tag with inconsistent form. No one doubts his ability but he has never kicked on or been able to replace his fellow countryman, Cristiano Ronaldo, at Old Trafford.
It all began so well. His first season in 2011/12 was a personal success. He scored eight goals and was crucial in the side's attacking play but since mid-2012 he has suffered a succession of niggling injuries and a gradual dip in form. Jeered by his own fans at times last season, his time might be up at the Red Devils.
He is already fighting with Juan Mata and Wayne Rooney to play in his favoured central position behind the striker, so another attacker would only further knock him down the pecking order. Hugely popular at his old club Borussia Dortmund, the Japanese star has never scaled the same heights he reached with the German club while playing for Utd. A talented attacking midfielder, with good Asian marketing capabilities, the Old Trafford club could get receive some good money for him with plenty of potential suitors throughout Europe.
Similar to Young, his Utd career started with such promise but over the last 12 months he too has suffered a rapid drop in form and seemingly lost the ability to create chances for his teammates. Premier League defences seem to have figured out how to play him. Despite his pace, he regularly fails to go past players or score which would be crucial in Van Gaal's favoured 4-3-3 formation. His career in Manchester, however, may be saved by his ability to play at right back but don't expect Valencia to be a regular starter.
His versatitly has been his downfall. He has been deployed in a number of positions, but he has stated he wants regular first team football in an central striker position. Van Gaal would love to have him at the club because he can play so many roles, but Sanchez's arrival would only further encourage him to look elsewhere.
