The picture below the odds movement for Munich vs Zagreb. It's looking stable.

The huge gap in odds from either of club tells Bayern Munich most likely to win the game easily. I think it makes sense. They're unbeaten in their last five home games. They're facing a weak team, Zagreb.
And i see Zagreb has no chance to win against Bayern Munich. Their record is 3 wins, 1 loss, and 1 draw. It's not bad. But, those stats don't convince me they can beat Bayern away.
But i think the odds's not worthy enough (too small). And over 2.5 seems pretty good enough to bet in this game.
To predict the result of Munich match in the UCL is not too difficult because the guarantee of victory looks more certain. On the one hand, Zagreb is not an equal opponent for Munich and will not put any pressure on Kompany.
But the problem is that Bayern Munich before appearing in the UCL must face Holstein Kiel who once defeated Munich in the DFB competition. Well, this is the pressure for Kompany who must manage the players properly so as not to experience defeat in 2 competitions at once. And if in the domestic match Munich will appear with second string players, Holstein Kiel will most likely still be able to hold a draw against Munich.
Betting on over 2.5 in the UCL match might be the right choice, but to bet on the match against Holstein Kiel, we must be careful and prefer to see the formation used by Kompany in the match this weekend.
