Manchester Utd v Portsmouth

Gary Lineker presents live coverage of the FA Cup fourth round tie between Manchester United and Portsmouth at Old Trafford.

Red Devils boss Sir Alex Ferguson has a won the competition a record five times as manager but only once since beating Newcastle in the 1999 final.

Portsmouth are the Premiership’s surprise package this year and in Harry Redknapp have a manager who knows a thing or two about cup shocks against United. He masterminded West Ham’s 1-0 fourth round win at Old Trafford in 2001 and was in charge of Division Three Bournemouth when they upset the Red Devils in 1984.
