Placing a bet on Barcelona for 1.37 could be a good bet. But would Barcelona be consistent enough to win this again? So far they have played well and won a lot, but this team is a young and in some places inexperienced team, sooner or later you will have to deal with a breakdown. Mallorca does not have a good team. If everything goes as it should go then I suspect Barcelona will win this 1-3 for example. But 1.37 is also a low odds to bet a lot of money on it. Perhaps it is more interesting to bet on the over or under total number of goals.
Barcelona have always been consistent since the beginning of this season. Barcelona vs Mallorca won't be difficult to Barcelona. I never remember to watch Barcelona this season having tough time to win their games. Xavi has made Barcelona not to struggle with anything to win their game. Mallorca players are not strong to change Barcelona.
Barcelona are in good shape and are likely to get all three points against Mallorca who have lost five of their head to head meetings. I see history repeating itself, I don't think Mallorca will stand a chance against Barcelona, Xavi has improved the team so much, they have recruited new players who have made the team even stronger. It will be difficult for Mallorca's defense to hold out Barcelona's attack.
