The sale of the Englishman would completely undermine the new United manager.
Chelsea have had another bid for Wayne Rooney rejected by Manchester United as it becomes increasingly more likely that the Englishman will leave Old Trafford.
However, by selling the forward to a direct Premier League rival the Red Devils run the risk of conceding the title through the sale of a key player.
United won the league for a record 13th time last season under the guidance of legendary manager Sir Alex Ferguson, an achievement largely attributed to new signing Robin Van Persie.
Yet whilst Rooney may not have had the best year at the club, the 27-year-old is the top-scorer during Ferguson’s 27 year reign at the English champions and has a great influence on the team’s success.
Since a transfer from Everton in 2004 aged just 18, the striker has gone onto win five Premier League titles, two League Cups and the Champions League in 2008.
Rooney has scored an impressive 197 goals in 402 appearances for the Red Devils and has also provided 102 assists to become a vital part of the starting XI.
By letting the England international leave for the Blues it would completely undermine new boss David Moyes’ first season in Manchester, as well as possibly tipping the balance in terms of talent at the two rivals – such is the influence of the player.
Whilst it is a well known cliche in football that a club should not keep an unhappy member of the squad, Rooney has tried for a move before and then changed his mind and had further success with United.
Likewise, the psychological damage of losing the striker to Stamford Bridge coupled with the obvious advantage Chelsea would have on the pitch, would essentially damn Moyes’ debut term before it has even started.
