The 22-year-old enjoyed a fruitful loan spell with Crystal Palace last season, scoring two goals in 25 appearances.
"Chelsea have told him he's going to be a part of the team this season and, if that is the case, they haven't lived up to that yet.
"If I were Loftus-Cheek I would be battering the door down in January and saying, 'that's it, I need to get away'.
"And not on loan, get away from Chelsea properly and build his own career.
"He's had the taste of playing first team football at Palace and obviously he loves Chelsea, but it's not happening for him there.
"He's got to play. He's too talented not to play, we've all seen that."
