LONDON: Chelsea can cement their position on top of the Premier League with a win over Birmingham on Saturday, while new Manchester City boss Roberto Mancini gets his first taste of English soccer against Stoke.

With second-placed Manchester United not in action until Sunday's clash at Hull, Carlo Ancelotti's Chelsea will move seven points clear of the reigning champions if they can defeat Birmingham at St Andrews.

But Ancelotti, whose team have spluttered of late, would be wise not to take Birmingham for granted.
