10. Wayne Rooney | Value: £40m
Wayne Rooney is Manchester United’s best player. When he plays well, so do the rest of the team. But when he’s off-form, the Red Devils tend to suffer.
Rooney is now 28, so his value may have decreased over the last few seasons, but United could still fetch around £40m for the England international’s services if they opted to sell to the highest bidder.
The tenacious striker guarantees goals and assists, while his work ethic is second to none.
Fortunately for Manchester United and their supporters, however, Rooney looks set to spend the rest of his career at Old Trafford.
