Sir Alex Ferguson is facing his biggest crisis since Wayne Rooney's revolt last season with Rio Ferdinand defying his call to join the anti-racism drive on Saturday.
Having deftly tackled the Rooney issue and asserting his authority by disciplining the talismanic striker for breaking Christmas Day curfew among other run-ins, Ferguson has been stunned by the latest challenge to his authority at Old Trafford where his word is law.
Ferguson is likely to weather this latest storm but Ferdinand's career at Manchester United seems to be well and truly over since his talents are on the wane.
Add to this is the disappointing form of Mexican international Javier Hernandez who has become surplus to Ferguson.
The 24-year-old enjoyed a sensational start to life at Old Trafford, when he joined from Guadalajara in 2010, scoring 20 goals in all competitions in his maiden season in Manchester, but he has been able to muster only seven appearances so far this season.
It has been widely reported that Atletico Madrid are looking to sign Hernandez to replace Radamel Falcao who is sought by the likes of Chelsea, Manchester City and Paris Saint-Germain.
The Spanish side are reportedly preparing to offer £12 million.
Italian Serie A side Fiorentina are also interested in a move for the youngster, but are thought to only be willing to offer United £8 million.
With United having the most in-form strike-force in England in Danny Welbeck, Wayne Rooney and Robin van Persie, Ferguson would have no hesitation in off-loading Hernandez in January.
