Messi is closing in on Gerd Muller's goal scoring record.
"He rested last week and we know that he always wants to play. It's a Champions League match and he's excited to play. If he's on the pitch, it'll make us stronger," said Vilanova
The manager played down Messi's assault on Müller's record: "We have to be as natural about this as possible. Messi has the chance to beat the record, but it will be more difficult if we're all focused on him. However, I think he's used to the pressure."
