The Arsenal midfielder has not played since January, with the most optimistic prognosis that he could be back in action before Christmas.

Rosicky has been sidelined by a hamstring injury which eventually required surgery in May, but his initial comeback date of September had to be shelved when he suffered a setback in his recovery.

The Czech Republic international has even had to cope with rumours that his career could be over, a situation compatriot Cech understands only too well.

Chelsea goalkeeper Cech spent a lengthy spell on the sidelines after suffering a fractured skull against Reading in October 2006.

And he has told Rosicky that his luck will eventually change and to remain focused on getting back onto the football field.

Serious

Cech told his personal website: "Tomas lives for football, he works a lot on himself, although it must be mentally very difficult.

"He must somehow get over the last phase of the treatment. Once the luck turns to him, everything will get better very quickly.

"I can imagine well how hard it must be if he does not know when he will return on the pitch.

"They also told me that I might get back in five months or a year and a half. He is in the same situation.

"He has not played for eight months and it is still getting longer. Moreover, he has never had such a serious injury before.

"It will not take much time before a player with such a talent gets into his usual form. He will only need a few games to get back to shape."
