I think the Real Madrid option for Xabi is too early. I think he needs to prove himself a little more. He can stay at Bayer Leverkusen for another year or consider the Liverpool option. I think Xabi can be successful in both options. If Xabi leaves the team at the end of the year, other big teams in Europe can easily make offers to the Leverkusen players who made history this year. They even transfer them. But if Xabi stays for 1 more year, I don't think the players will want to leave. They owe Xabi a debt and I think they need to pay these debts.
Yeah, definitely, Xabi Alanson has to do more, like spend some more time to prove himself because Real Madrid is a big club and there is a small mistake you can sack or replace. So Xabi Alonso will have to spend some more time to be 100% sure. The Uefa Champions League is a big competition, and for this, different tactics and concepts have to be made. For coaches who do not have experience with the Uefa Champions League, it becomes difficult for them to play in a hard competition like the UCL.
Anyway, the coach of Real madrid is Carlos Angeloti and he is performing very well, He will become the La Liga champion and he is also performing well in the UEFA Champions league. But now everything depends on Manchester City. If he tries to get a chance for victory then it will be possible for him to stay; otherwise, Real Madrid will increase the trend towards the new coach, which is definitely Xabi Alonso. But it was just a lay talk; let's see what happened next.
