LONDON — It has been a good week for Chelsea without kicking a ball as it prepared for Saturday's Premier League summit showdown at Manchester United.

Wayne Rooney's ankle injury sustained in the 2-1 defeat at Bayern Munich means he will miss the game, while Arsenal's challenge for the title has been hit by midweek injuries to Cesc Fabregas, Andriy Arshavin and William Gallas.

If Chelsea or United wins its remaining fixtures, it will be champion.
