Rio Ferdinand has revealed that he and former Manchester United team-mate Wayne Rooney would engage in foul-mouthed clashes in 'every training session' during their time together at Old Trafford.
The duo won a host of trophies and accolades during the eight years they spent together at United and also often played together for England.
Ferdinand was an integral part of the time that won three consecutive Premier League titles, while Rooney is the club's all-time leading goalscorer.
