With Alonso as Real Madrid's headcoach, and a former player of Madrid, and a club which he played for many years, he's going to have a great achievement and success with Madrid, considering his successful managerial record with Leverkusen.
I believe they have higher opportunity in this competition to lift this very trophy aside, PSG and Chelsea two current champions.
Real Madrid is very lucky to have a coach like Xavi Alonso come into their rescue, because they had a poor last season under Carlo Ancelotti, and I do believe Alonso will get Madrid right back on track with his tactical system of play.
Don't count Alonso's chickens before they hatch.
He has nothing achieved yet, Real Madrid's performance at the CWC is mediocre and they will have one of the strongest teams against them in Europan football, namely Barcelona.
The duels with Barcelona could cost them a lot. They could lose the Copa del Rey, could lose the league title and who knows where else they are going to play each other.
Alonso will find out that it is not as comfortable to work for Real Madrid as he is used to. The pressure is on a different level and heated discussions arise after every draw. That wasn't the same in Leverkusen.
