Arjen Robben v Gael Clichy
Robben scored against Bayer Leverkusen last Saturday in his latest comeback game and is capable of inflicting so much damage if Clichy does not shackle him.
Daniel van Buyten v Sergio Aguero
Van Buyten played four games on loan for City in 2004 but was released because the Blues could not afford him. Now 33 and showing signs of age, he must quell the threat of Aguero, who cost £38m and has scored eight goals already this season.
Thomas Muller v Vincent Kompany
Muller is very effective for Bayern without being particularly pleasing on the eye and will test Kompany's defensive qualities to the limit.
