Actually I see Kloop also suitable if he goes to Bayern Munich. But his statement about his future seems to have been answered. So that seems unlikely to happen. Instead of Xabi I think Zidane could be another alternative. Because I read he is ready to work again at the moment.
Bayern Munich's chances in the UCL are still very big. They only lost 0-1 to Lazio in leg 1. Furthermore, they have many opportunities because of leg 2 in Germany. I am very sure they are able to qualify for the last 8.
Klopp's agent said plans for a year-long holiday have not changed and 100% will not change. And we know that Tuchel will leave in the summer. It turns out that in order for Klopp to end up in Bayern, the next coach after Tuchel must also fail. Theoretically this is possible (Bayern lost all their luck lol), but it is unlikely given the fact that in the summer they will hire someone from the top (possibly Zidane, perhaps Xabi).
As for the chances in the Champions League, they are great against Lazio, Bayern is a big favorite before the return game, but in general the bookmakers have lowered Bayern's rating and now they are ranked worse as title contenders than Arsenal (now Bayern is in 4th place).
