Eintracht Frankfurt is a fairly strong team in the Bundesliga, and they will likely become even stronger this season, having won their previous two matches. Therefore, I'm not confident that Bayer Leverkusen can win if their next opponent is Eintracht Frankfurt, who are currently in second place, just behind Bayern Munich in the standings. It seems Ten Hag will have to work hard for that, as a tough opponent will be coming to Leverkusen's home ground next week, and he will need to get a good result to aim for three points at the start of the season.
Frankfurt, Koln and Bayern Munich have won 2 matches so far. No other team has won 2 of their matches. Frankfurt seems to be a strong team. However, it is not possible to make such a quick prediction about whether the team will be able to play well in the long run. Personally, I do not think that any team in the Bundesliga will be able to compete with Bayern Munich for the title. I am sure that Dortmund, Leipzig and Leverkusen will not compete for the title. The performance of these three teams is quite erratic. In the Bundesliga, we will only see Bayern Munich's dominance this season.
