Chelsea manager Jose Mourinho wary of Aston Villa challenge

Chelsea manager Jose Mourinho says forthcoming opponents Aston Villa are capable of beating any of the Premier League title contenders.

Mourinho praises Villa's away form last season ahead of his side welcoming them to Stamford Bridge on Wednesday.

The Portuguese boss, thought to be interested in signing Manchester United striker Wayne Rooney, admits it is "difficult to speak to about players from other clubs," and explains how he will have to "protect" midfield favourite Frank Lampard throughout the season to ensure he stays fresh.
