“Celtic are a tough team to play against and they’re like warriors on the pitch,” said the Brazilian.
“We have already suffered against the Scots in trying to beat them.
“Last season Barca failed in Glasgow against Celtic. We were just thankful it wasn’t a decisive match in the group for us.
“Now it’s about a piece of sporting revenge.
“Celtic are renowned for their character and pride. They always offer maximum effort on the pitch and that means it’s never easy for their rivals. Especially in Glasgow, where they are strong.
“Can Celtic make third position in the table? That is possible because they play with so much commitment in every match in Europe.”
