Chelsea keeper Cech could be forced to retire early due to injury!!! Chelsea keeper Petr Cech could be on his way out due to persistent back and knee injuries. The astonishing claim was made by the Blues' backup stopper Thibaut Courtois in an interview on Spanish radio station Onda Cero. "I know he has problems in his knees and on his back," said the 19 year-old, currently on loan at Atletico Madrid. "Chelsea's goalkeeping coach told me he doesn't know how much time Cech can play at the top level." http://www.mirrorfoo...icle816553.html
