Chelsea defender Jose Bosingwa has no concerns marking Barcelona star Lionel Messi tonight at the Nou Camp.

"It is not problem marking Messi," he said. "I'm prepared for the challenge.

"Messi is a big star world wide but it is possible to stop him - with patience and calm. You need to keep him under pressure.

"I have experience playing with Porto and Portugal against big players and now with Chelsea. I do not fear the Argentine."
