Indeed, no one expected Las Palmas to be able to beat Barcelona, before the match started, everyone believed that the match would be easily won by Hansi Flick squad. Barcelona efforts to maintain the top position in the standings are now threatened by Real Madrid, in my opinion this is a big problem for Barcelona in the future. Real Madrid will not waste the opportunity to reduce the points difference that has been created, they are targeting 3 points when hosting Getafe, besides Ancelotti is trying to get out of the pressure after the defeat to Liverpool in the Champions League.
Of course, no one expected Barcelona to lose at home, but Las Palmas proved it. This is why sometimes there are gamblers who bet their money on non-favorite teams, of course because every now and then they will get a big win because the odds they have are very high.
Many people are clearly disappointed with Barcelona's defeat today, not only fans and players, but also gamblers who chose Barcelona in their bets. Even I don't believe in a draw for that match, but in reality Barcelona lost even though they dominated the match.
