The Portuguese defender has been handed the task of marking Messi in the first leg by Chelsea boss Guus Hiddink.
“I’m prepared for the challenge. It is no problem marking Messi,” Bosingwa told the Daily Star.
“Messi is a big star worldwide, 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.”
