Der Klassiker could either reopen the Bundesliga season or effectively crown Bayern: if they win, they go 8 points clear with 9 games to go. On the other hand, Borussia Dortmund have nothing to lose. They’re 15 points clear of third place. They aren’t normally the kind of side to vary their style based on the situation, but here you expect Thomas Tuchel to be even more attacking. They’re pretty much at full strength anyway, apart from Sokratis, whereas Bayern have the usual suspects out defensively (Boateng and Javi Martinez above all). The natural reaction is to back the over 2.5 goals. That’s 1.73 with William Hill, which isn’t great frankly. You’ll get better value looking at something like 2nd half over 2.5 goals which is 4.33 with William Hill (or, if that’s too much for you, go for over 1.5 goals in 2nd half, which is a more manageable 2.00). If you’re looking for a straighter bet, both score no draw is at 2.5 which is decent value, too.
