It is like a gift for Leverkusen this week.
Because among the title contenders, they are the one playing the easiest game. It is a home game against Holstein Kiel.
This team are officially the worst one in the league by being at the bottom of the standings as well. Their defense is horrible. Bayern Munich scored 6 goals against them.
I simply expect Leverkusen to improve their unbeaten streak to 6 games in all tournaments. But for betting purposes, their straight win pays out nothing. Therefore adding some fun into it by expecting them to win by at least a gap of 3 goals @1.69 makes more sense.
You are to an extent right on this mate, Bayer Leverkusen have the most easiest fixture among the three teams that I think that are capable of competing for the title, and I think the most easy option when staking on this game is to go for a direct winning for Bayer Leverkusen, but just as you rightfully said, the odds will be very small, but if I will be the one staking it, I will go with the option of home team to win in first half, though it's a risky game actually, but I believe that it's not that difficult for Leverkusen to achieve.
Then as for the Union Berlin vs Dortmund game, though Borussia dortmund are actually the favourite on papers, but it's not going to be an easy game, mostly since Dortmund are playing away, but it's definitely going to be a fascinating encounter between them, so I will be going with the option of draw or GG.
