Sir Alex Ferguson on Man Utd, retirement and David Beckham

Ahead of his final match in charge of Manchester United, manager Sir Alex Ferguson looks back on his decision to retire - and reveals what he will miss most about the club.

The 71-year-old will step down as United manager at the end of Sunday's away match against West Brom after 26 years in charge at Old Trafford.

Speaking at his final pre-match news conference, Ferguson also pays tribute to the "amazing" David Beckham, who himself is retiring from the sport at the end of the month.
