A strange clash at the top of the Premier League this weekend with the visit of Manchester City (3rd) to Southampton (2nd). A high-risk match if ever there was one, but the Sky Blues must win if they want to overtake their hosts and draw closer to the invulnerable Chelsea (1st). The Blues should have an easy time of it at Sunderland (14th). Manchester United (4th), the other big contender in action this weekend, can stay in touch with the leaders if they win at home to Hull (17th). Liverpool (12th), meanwhile, will be hoping to regain their lost form against Stoke (11th).
