I doubt it. After the Sunderland game we have Kazan again so I don't think he would play 3 games in a row whereas Ba, who scored the cracker, would sit the league game.
That's it, meaning we just can't send there reserves and youth. If that was 4-1 it would be safer. Now we can't really rest the players before the Man City game.
4-1 would have been completely different and game over. 3-1 is still dangerous I believe. Luckily, the second leg is played in Moscow and not in Kazan.
