Barcelona coach Pep Guardiola admits Lionel Messi is struggling with toothache.

Messi could be missing today against Real Zaragoza due to the complaint.

"He's gone home and tomorrow we'll see how he is. He's in a lot of pain and it's very swollen," Guardiola said.

"We're trying to make every player feel important and Messi knows that he can enjoy himself on the pitch thanks to the work of his team-mates."
