Colin Murray introduces highlights of the day's two Premier League fixtures. Chelsea entertain Liverpool at Stamford Bridge looking to avenge a 2-0 defeat at Anfield earlier this season. Carlo Ancellotti's side need a victory to maintain their hopes of winning a second successive title. At Upton Park, West Ham take on Birmingham. The two sides shared the points in an entertaining match at St Andrew's earlier this season as the Blues roared back from 2-0 down to snatch a point.
