Bayern Munich have been struggeling during their last games but however they are the leaders in the Bundesliga with 20 points. The German believes his team has to improve a lot in order to be able to win the Champions League.
"The first Champions League match against Atletico in Madrid has shown that our performances are not yet good enough for the top level. To win the Champions League for the second time we must improve several things. I think that it will be important to find the right balance between feeling relaxed and tense.," he wrote.
He added: "After a big win against Gladbach at the weekend, we made our ambitions clear once again - we want to be leading the Bundesliga and our aim is a fifth title in a row. In order to reach that goal, we must take a clear look at our rivals and be spot on when analysing our opponents".
