The future of Chelsea's goalkeeping coach Christophe Lollichon is now in doubt, with the assumption he will follow Petr Cech, a client he has worked with for most of his career, to Arsenal.

However, it is believed that is not necessarily the case as things stand and he could still opt to stay at Chelsea and work with first choice Thibaut Courtois.

The Belgium international increased the speculation over Lollichon's future by revealing he has recommended his former coach at Genk, Guy Martens, to Chelsea.

Courtois said: "He is the best goalkeeping coach ever. I learned everything from Guy. I never had this with other goalkeeper coaches.

"I have given his number to Chelsea and even said that he is available. He can help goalkeepers get better."
