Real Madrid's odds is moving up. It's because they have a very shaky defense, and they're also losing in their last game against a bottom team in La Liga. They also played away game, which is obviously affect their morale a bit.
Their odds is moving up from 3.05 to the 3.15. It clearly says about how bookies are doubting them to secure good aggregate in this away game. However, i personally won't take it.
In this game, i believe they will score, but it's obvious their rival is about to score as well. So, i think BTTS is the right choice to bet. The odds received by them and their rival give me confident they will score with possibly draw.
The bookies are giving quite reasonable odds due to Madrid inconsistency this season. To be honest Madrid stability is still far from expectations. The attacking trio has not given a strong aura of familiarity. Not only is Madrid defense fragile, Arsenal will also benefit if they can provoke Vinicius emotions later on the field and will disrupt Ancelotti game strategy.
