Manchester City defender John Stones told his team they needed to respect Celtic's quality ahead of their Champions League clash.
Pep Guardiola's side are flying high in the Premier League ahead of the meeting in Glasgow on Wednesday.
Stones, however, warned City they needed to perform against Brendan Rodgers' outfit.
"You have to show respect to the opposition. They've obviously got quality, that's why they're in the Champions League," he said, via ESPN.
"The teams that are in it, deserve to be in it and we've worked hard to get in it.
"It's one that we'll be fully up for and I'm sure they will be as well. It's going to be exciting for everyone."
"I don't agree with us being favourites. It's going to be a difficult game," the Brazilian said.
"Of course, they had a painful defeat for themselves and the fans, but maybe that's one of the reasons they will step onto the pitch with a lot more concentration, motivated to try to win this home game.
"So we'll have to be very careful and stay very focused to not allow that to happen."
