My prediction is so 2 1 Zenit.
some information about Zenit: it's the second in the premier league in Russia. the last match we lost, Terek(it played against thsi club) won and became the first(it's an sensation cause Terek isn't the top club). Adn undoubtedly it's a slap in the face which will help us in this match. But Zenit never began a start in CL good so I don't eliminate that we lloser this match.
About Malaga I didn't hear much, but I heard that the start of it in La Liga was good.
