That Zenit goalkeeper must surely be on drugs. Either that or he is simply one of the worst that I have seen in my life. The first goal was already bad but the second is just epic. Maxi Pereira also seemed to be inspired by that clown's antics in their 3rd goal.
Zenit should have Malafeev, a real (and pretty good btw) keeper in the return leg and you will be missing Aimar (suspended). Not clear how bad is Rodrigo's injury as well. In any case I think you keep being favourites to go through.
