I couldn't figure out your stance here, as you sounded both sarcastic and straightforward at the same time.
Well, history has shown that preseason could be used to judge the winner, and it has failed in many cases as well. This is why we are waiting for the actual tourney to start. However, Bayern will always be the most preferred winner, especially with the inconsistent performance of Leverkusen and the departure of their hero coach Xabi Alonso. I don't have so much faith in Erik ten Hag.
Eric Ten Hag may not have proven so much in the preseason that he is the perfect man for the managerial role for next season, but since we can’t use preseason matches to equate to how managers will perform during the season, we just have to give him a chance to prove himself worthy of the position when the season begins. Just like how Bayern Munich has shown that they’re the one formidable team to win the Bundesliga next season and have shown that great performance in their preseason games too, it is not a certainty they will not fumble during the season when it begins.
The season Bayern Leverkusen won the trophy, they still did their best in the preseason but end up losing out on the trophy title to Bayern Leverkusen. Every certainty and conclusion we can draw in this match will have to be when the season begins and have gone halfway before we can begin to have some conclusions on which team has the tendency of winning the trophy. So any conclusion we draw now is just a speculation which is not backed up by any facts to be trustworthy of happening.
