Real Madrid played at home and only scored 1 goal.
I didn't watch the match live, but watching the replay on YouTube, I saw that after Kylian Mbappé scored from a penalty kick, Xabi Alonso looked dissatisfied.
Of course, the coach was dissatisfied with Real Madrid's poor performance, wasting so many chances.
If Real Madrid continues like this, Barcelona will easily dominate the top of the standings and win the title again this season.
This is definitely a concern, I watched the match between Real Madrid vs Osasuna live and I didn't like Real Madrid's performance either. Maybe they exchanged the ball a lot but what's the point of exchanging the ball if they can't attack well or they can't score goals. Real Madrid players got several chances especially at the beginning of the match Vinicius Junior passed a ball inside the opponent's D box to Mbappe with a great dribble but Mbappe couldn't finish the ball well. But Mbappe should have taken advantage of that chance.
Real Madrid got a penalty, it's their luck, if Real Madrid hadn't got a penalty then they would have finished the match with only one point. Barcelona secured a big win in their first match, on the contrary Real Madrid couldn't do that so if there is no big change in performance then Barcelona can go to the top of the points table like last season.
Now is not the time to worry about Real Madrid and before criticising them, we must give Xabi Alonso time. He is still new to the team and very new to a big team like Real Madrid. So to get the best out of him, we must give him a few games and give him time to adapt to Real Madrid in La Liga. We should not worry or criticise Xabi Alonso or Real Madrid before at least 10 matches of the season have passed. They will definitely perform well but we need to give it time.
