Colin Murray and guests look back at the day's Premier League matches and provide the last word on the rest of the weekend's action. Title challengers Manchester United and Chelsea were both playing today, with United hosting arch rivals Liverpool and Chelsea welcoming newly promoted Blackpool. A highly charged atmosphere was guaranteed at Old Trafford as the two most successful clubs in England went head-to-head. Park Ji-Sung's winner for Manchester United in the corresponding fixture last season ended a run of three straight defeats by Liverpool, although United were ultimately unable to surpass Liverpool's 18 league titles.
