Porto v Bayern Munich

"The draw is the draw," Bayern Munich coach Guardiola said after the draw.

"All teams have a special quality. Porto and Shakhtar were in the same group, so we have already watched a few of their matches," he added.

"Porto have a great team and a beautiful stadium. They are very strong physically and attack with a lot of pace, but in the quarter-finals you can't expect an easy match," he concluded.

"The atmosphere in Porto is very heated. I witnessed the Porto fans during the 2004 Champions League final against Monaco," said Bayern goalkeeper Manuel Neuer.

"The atmosphere was amazing. With these fans it won't be easy for us, but we have played in many different stadiums with varying atmospheres and we will know what to expect."

"Bayern were one of the least desirable opponents, but nothing is impossible − the tie starts 0-0," Vitor Baia, former Porto goalkeeper said.

"Last time we came across Bayern [in the 1987 European Cup final] we also weren't favourites, but we won. On a perfect day with a perfect game, anything can happen," he added.

Juventus v Monaco

"Juventus are among the biggest sides. They are the favourites. We're lucky to have the second leg at home. We'll try to make the most of this quarter-final," Monaco coach Leonardo Jardim said after the draw.

"We've got a chance to get through to the next round, that's the most important thing. We'll give it a good go," said Juventus legend Pavel Nedved.

Atletico Madrid v Real Madrid

"Atletico are a competitive side and we have faced each other a lot this season and know each other well," director of institutional relations at Real Madrid Emilio Butragueno said.

"They're a side who know how to compete, they let in few goals, are good from dead balls and get the best out of each situation. We will see if we can beat them and come back for the draw for the semi-finals," he added.
