Xabi Alonso must try to moderate the team and make the group more cohesive, with the team he has he can certainly do very well and decide to impose himself both in the league and in the Champions League calmly, he just has to work with his players, He would do well to make a retreat and talk to them
The season has started, and there are two La Liga matches to be played today. But for Real Madrid, there is still time to develop tactics and the team's needs, so Alonso can organize them properly and prepare himself as thoroughly as possible for his debut season with Real Madrid. I also hope he has no trouble getting Real Madrid on a strong path, because all the players at Real Madrid are great players, even though they still need more detailed guidance from their current coach.
No doubt Alonso has a very talented squad but his success will depend on how well he brings the group together and builds trust on and off the pitch. New season has just started and he still has time to shape his tactics and adapt the team to his style before the pressure really builds. Since Madrid's players already have the quality, they just need clear, detailed guidance to perform as a unit. I do believe that Alonso certainly manages that and dominates both La Liga and the Champions League.
