Barcelona will be out for Celtic revenge - Alves
Celtic Park in the Champions League group stage last campaign but the Spaniards will get the opportunity to atone for that result after being drawn together in Group H of this season's version of the competition.
"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."
