Ever since Wayne Rooney joined Manchester United from Everton in 2004 for a fee of £27m, he has helped guide them to glory on numerous occasions - becoming a fan favourite and English hero in the process.
However, recently he has been out of favour at United due to the arrival of Robin van Persie at the start of last season, which has seen him move into a deeper role and even onto the bench on occasions.
Rooney was not happy with being second best to Robin van Persie, and towards the end of last season he was thought to have handed in a transfer request. Nothing has changed since then, and a host of clubs are thought to have an interest in him - including fierce rivals Chelsea who are now managed by Jose Mourinho.
The Blues seem to be the front-runners to capture his signature, but David Moyes has been holding firm and has already rejected two bids for the player. If Rooney was to join Chelsea, no matter how much he was purchased for, it could cost United the Barclays Premier League title. There are many reasons why United shouldn't sell Rooney, which will be explained below.
To start with, Rooney can play in many positions. For most of his career he has played as a striker where he continues to score goal after goal for United every season. However, over the last few years he has dropped into deeper roles, playing as a centre attacking midfielder and even occasionally a centre midfielder.
He has adapted to these positions very well and has proved to be just as effective in these roles. 12 goals and 10 assists last season show that he can be creative whilst still being an assassin up front.
The second reason is losing a player like this to your rivals is a massive mistake. If Chelsea were to have this player then they could have the edge on the other title contenders and ultimately win the league.
If they were going to sell then it would have to be to a non-league rival like Bayern Munich, who are also thought to have a strong interest in him. Even so, why would you want to sell Wayne Rooney?
He's one of United's star performers and Moyes should do all he can to keep him.
