The bettors are surely confident that Madrid will easily defeat Mallorca, which is not a strong team in La Liga. Previously, Mallorca had also been defeated by Barcelona. However, I don't expect Madrid to score a big margin in this match. So far, Madrid has only been able to score 3 goals against Real Oviedo. Therefore, it's likely to end 2-0.
This will be a good win for Real Madrid tonight and the odd is 1.21 in the platform I use. I refuse to play it based on goal which would have given me bigger odd because the match can produce many goals or few goals, it is not clear since the season is just starting and Real Madrid have not really found their strength. This is why prefer betting on win which has higher probability and to make the odd bigger, I combined that with Galatasaray win which also have about the same odd and PSV win to give me something close to what you played.
