Robert Lewandowski had the game of his life against Real Madrid on Wednesday, scoring four goals.
Sitting on a 3-0 aggregate lead, Real Madrid were hardly going to fail to make it past Galatasaray, but Ronaldo's 8th minute goal made the rest of the match in Istanbul a formality, despite the hosts' repeated attempts to make things interesting.
Lionel Messi will get a lot of touches on Wednesday, and he will have a serious impact on the game. It'll be Sami Khedira's job to make sure Messi doesn't get the ball wherever he wants, whenever he wants it.
Real Madrid visits today the stadium in which the club won its 7th Champions League title (20:45 CET). Ajax's condition of weakest team in the group makes this game a must-win one.
