Zenit vs Celtic prediction

Zenit must win this match at all costs and to expect one goal of theirs at their own stadium is a clear sign of normality. Celtic may be more problematic considering scoring a goal but I do not think they will be too problematic as Zenit seem not to be in good form defensively and make a lot of mistakes. Celtic are very well positioned to score a goal and decide the outcome of the game. The odds for btts are too high to miss considering there is not big difference between the teams as seen in the first leg. Zenit messed it up semiseriously in the first leg and today they will probably pay the bill.
