Man Utd, Chelsea, Arsenal and Liverpool all play their respective return european ties this week and I can't see any of them getting through.
Liverpool stand the best chance being already 3 - 1 up against Beyer Leverkusen, but it will not be beyond the home team to get a 2 - 0 victory.
The three other teams will need to produce some good displays to turn around their ties, but I am not that optimistic
