Xabi Alonso contract clause could open the door to Liverpool, Madrid and Bayern Munich

Xabi Alonso's Bayern Leverkusen have been doing very well in the Bundesliga since the Spanish coach arrived. They currently sit top of the Bundesliga, ahead of Bayern Munich and Borussia Dortmund">Borussia Dortmund, with 19 points from seven games.
According to reports from 'BILD', Xabi Alonso has an agreement with Bayern Leverkusen to leave the club next summer. Although he has a contract until 2026, there could be a clause in his contract that would allow him to leave for Liverpool, Real Madrid and Bayern Munich.
The possibility of being Jurgen Klopp's replacement is the most complicated because the German's position is so settled. Bayern Munich hired Thomas Tuchel in March and he is expected to be given more time at the club before a change.
Real Madrid could be the clearest possibility for the Spanish coach as it seems clear that Carlo Ancelotti could leave the club this summer and join the Brazil national team when his contract expires. Mail Sport reported last week that Alonso tops Real Madrid's wish list.
“Coach Madrid? It’s September, it’s early days. I’m staying focused. We have started the season well, we want all the players to be focused. That’s why I have to be the first,” said about a possible move to Real Madrid.
