The retired defender said (per the club's official website):“You look at attributes you want in a centre-back and ask: Is he tall and good in the air? Does he have good presence? Is he quick? Does he take up good positions to receive the ball? Is he composed on the ball? Levi Colwill has those attributes – now he must keep learning and progressing.”Cahill insists that the English defender can form a great partnership with veteran Thiago Silva at Stamford Bridge. He added:“The manager will help him with that for sure. So will playing alongside Thiago [Silva], who has achieved so much in the game. He can soak up things from him, carry on learning and learning. It will be a big season for him. From the training I’ve watched, from what I’ve seen from him in games, it’s clear he’s got massive potential and is a very good player.”It remains to be seen whether Colwill can become a starter in Mauricio Pochettino's side next season."He hasn’t got the experience" - Frank Leboeuf urges Chelsea not to sign Premier League midfielderChelsea icon Frank Leboeuf has urged the Blues not to sign Brighton & Hove Albion midfielder Moises Caicedo.

What he showed last season was absolutely fantastic and one of the best players in his position right now. It’s not, for me, what Chelsea should look for.
