Rio Ferdinand has recalled the challenge of training with some of Manchester United's best forwards over the years - and how it was just as difficult as most Premier League matches.
Ferdinand cemented a legacy as one of the greatest Premier League defenders of all time in his 12-year stint at Old Trafford, where he claimed six Premier League titles, two League Cups and the Champions League under Sir Alex Ferguson.
The former England captain shared a dressing room with some legendary strikers over the years, including the likes of Wayne Rooney, Cristiano Ronaldo and Ruud van Nistelrooy.
