Vincent KOmpany is not taking any risk at this time. Kompany will certainly not want any key player in his squad to suffer an injury before the start of the season.
Especially after a summer with big tournaments like Euro 2024 and Coppa America 2024, star players are more exhausted than other years without big tournaments. Star players are smart and experienced enough to adapt well with a new coach and I see philosophy of Kompany is not too strange. Bayern Munich players are familiar with tiki taka because Pep used to be their coach for some seasons ago.
Harry Kane is the most important player and scorer in Bayern Munich's squad. If Kane faces an injury, it will be very difficult for Bayern Munich to continue their good performances next season. So Harry Kane is likely to be out of the squad for both friendlies against Tottenham.
Harry Kane is important for Bayern Munich to find goals and the player himself is fighting for a first team title in his career. A next season will be a big test for Kompany and Kane, to win titles together and upgrade their career together.
I would say that Bayern Munich will not play in this match aiming to win against Tottenham. Vincent Kompany will try to test his squad's ability in this match. At the same time he will experiment with his match strategy. Kompany is not an experienced enough coach. So it will be challenging for Kompany to keep the performance of this Munich squad stable.
In football, when you play a match, you want to win it but there are reasons to think that Bayern Munich and Kompany won't want to win this match with all costs. They will use it as one of last preparations before a new season, winning is best but if they can not win it or lose it, it's not nightmare with them. The point is what they will get from this match, from tactical trial and operations, player assessment and end this match without bad news of player injuries.
