Bolton boss Owen Coyle has backed Gary Cahill to play an important role in Andre Villas-Boas' rebuilding job at Chelsea.

Cahill has become Villas-Boas' first recruit of the January transfer window, with the 26-year-old England defender's move from the Reebok Stadium to Stamford Bridge finally being confirmed on Monday.

"I think there is - as with any player - room for expansion and improvement. He has now gone to an elite club who have aspirations of winning every competition they enter," said Coyle.
