To me the 2 biggest games tonight are Lille Vs Real Madrid and Aston Villa Vs Bayern Munich.
In both cases, home teams are underdogs and we have a very similar odds in both matches. You could get around x1.60 for an away team to win.
I'm not sure about Lille Vs Real, as I don't follow the French league, but as for the second game, I don't think it will be an easy game for Bayern, I think the odds are misplaced and AV should not be that much of an underdog. I wouldn't go as far as to say AV should be the favourite, but I expect it to be a quite even game, and therefore I think a double-chance bet for AV to win or draw is a good value bet and could yield you around x2.20.
It would be risky to take double chances to win and draw from Aston Villa, we know how Bayern Munich play in the champion league they have never been in doubt at all while Aston Villa is not a balanced opponent in my opinion, so there is still a possibility of Bayern Munich winning again with a large number of goals.
Still taking the @1.60 odds will be better and still likely to win.
LOSC vs Real Madrid is the away team that will win.
I don't really follow the French league but LOSC in their own league has only lost 2x and 1x draw while in UCL matches they still can't win last week at Sporting CP.
It's clear to me Madrid will win.
