Keane: Alex doesn’t know the meaning of loyalty

Roy Keane has hit back at Alex Ferguson, accusing him of not knowing the meaning of loyalty after the former Manchester United manager savaged one of his once most trusted captains in his autobiography.

Ferguson lifts the lid on his feud with Keane in his soon-to-be-published book My Autobiography, with the Scot claiming his authority at Old Trafford would have been undermined had he not sold the increasingly volatile player in 2005.

Alex Ferguson also revealed he warned Roy Keane life would be “horrendous” for his family if he didn’t patch up his differences with then Republic of Ireland manager Mick McCarthy in Saipan 11 years ago.
