Arsenal hero Ray Parlour is convinced Petr Cech is Chelsea's weak link ahead of today's FA Cup semifinal.

Parlour told The Sun: "If I was Arsene I'd be telling Theo Walcott to charge down that wing and ping in as many crosses as he can.

"Stick Emmanuel Adebayor in the box against Cech and something could give.

"On Tuesday, Cech wasn't just wobbly for the first goal. Towards the end of the first half a cross came in, he flapped at it and the ball hit somebody on the back - it could have gone anywhere.

"Cech is nowhere near as commanding as he was last season. His confidence is shot to pieces. I saw mistakes creeping in against Bolton last weekend."
