It looks like it will be a very busy summer at Old Trafford.

Manchester United are set to have their busiest transfer window for in several years, with Declan Rice one of five players the club are looking to sign. Ole Gunnar Solskjaer's side could also lose as many as six players as they attempt to overhaul their squad.

Aaron Wan-Bissaka (21), the Crystal Palace right-back, is also said to be on the club's transfer shortlist. As is Callum Hudson-Odoi (18), the Chelsea winger who has attracted interested from Bayern Munich. Hudson-Odoi has 14 months left on his contract at Stamford Bridge.
