I think odds for Leipzig winning (or drawing) are misplaced and are much higher than they should be.
Of course, I agree that Bayern is the favourite to win tonight's game, but odds of x1.22 for Bayern and x10.00 for Leipzig are a bit off, and I think betting a small amount on the underdog, or a double-chance bet (Leipzig to win or draw) of x3.50 is a good value bet.
Looking at the last 5 games (all competitions) Bayern has won only 2 of them, wile Leipzig has won 3. Leipzig's problem is lack of consistency, they have games when they get defeated conceding a lot of goals, but on their good days, their defence is really solid. They don't tend to score as often as teams from the top 3, but they could easily make a surprise tonight and steal some points from Bayern.
