LONDON (Agencies) - Manchester United moved five points clear at the top of the Premier League after staging a stunning late fight back to win 3-2 at Blackpool on Wednesday. Sir Alex Ferguson's side had gone 27 league matches without losing, a run stretching back to their 2-1 defeat against Chelsea in April last season. But that sequence looked in danger as goals from former United defender Craig Cathcart and striker DJ Campbell put the Seasiders 2-0 up at half-time.
