Fenerbahce superstar Roberto Carlos is convinced they will shock Chelsea at Stamford Bridge.

The Brazilian said: "Chelsea have problems at home. I watched them against Middlesbrough and they had tremendous difficulties to win.

"If we play well we will have chances and if we score one goal we will go through for sure.

"I spoke to everyone before the last game and said we should not be afraid of Chelsea's big names so that we could play our best football.

"We put them under pressure and got a massive victory which gives us huge confidence for the second leg."
