I do not have a view on the analysis of the Bayern Munich coach when facing a crucial match like this and usually the Champions League will put a little pressure on each coach and facing a much more balanced team will make everything different. Moreover, Barcelona has the advantage of playing at home so their motivation will be much greater even though if you look at the quality of the Bayern Munich players they are slightly more favored.
If you look at the head to head, of course Bayern Munich will be more favored because Bayern Munich also often wins when playing at Barcelona's home in the Champions League competition. However, it could be different this season because Barcelona has also started to improve this season so I just think that their match will be more intense even though the match will take place at Barcelona's home. Bayern Munich is a team that is quite feared by its opponents in the Champions League so they will not be afraid when they have to play at Barcelona's home next week.
