Gary Cahill is set to have a brilliant career for Chelsea and England according to his former boss Owen Coyle.
The pair will come face-to-face this weekend for the first time since the 26-year-old left Bolton for the capital in the January transfer window.
The defender has made just one Premier League appearance for the club since his protracted £7m move and his start against Napoli in midweek was only his third for the West London side.
But, despite an indifferent start to his time at Chelsea, Coyle insists the England man will go on to have a glittering future for both club and country.
Coyle said: "Gary is an outstanding player, who is conscientious, who cares and who doesn't like losing at any time.
"There is no doubt that he will have a terrific career at Chelsea.
"It is always difficult in the January window when players are thrust right into it. I think Chelsea were clever in giving him a couple of weeks' training with the players before he stepped into the team.
"The team has had some indifferent results and Gary is part of that, but there is no doubt that he will achieve big things at Chelsea."
