Sven Ulreich should be the goalkeeper who will get many chances at Bayern Munich if Manuel Neuer is injured or no longer gets a contract extension. But considering Sven Ulreich's age, which is already 34 years old, it is important to get a goalkeeper who is the younger of the two.
That's why other names have sprung up like, Yasin Bounou, Livakovic, Yann Sommer who plays for Gladbach, even the latest rumor is Emiliano Martinez. however, so far neither one has actually signed a deal with Bayern Munich. although actually, Dinamo Zegreb or Sevilla. has responded to the needs of Bayern Munich. it's just that, so far there has been no official statement regarding who will replace Neuer later. so, we will just wait until there is an official statement from Bayern Munich.
The biggest factor about Yassine Bounou is going to be his age. He is already 31. And I would say he is just another average goalkeeper. He is not even above average. At least that’s my opinion about him in club competitions. In the World Cup, he did show some good performance. But I also agree with you that he is probably not going to be able to continue that performance in club competitions.
Sven Ulreich is a better goalkeeper compared to Yassine Bounou in my opinion. But here comes another problem. He is also 34 years old. But I still think that he’s going to be better. And this could be a good thing for Bayern Munich because they might want to keep him for one season and if they get another better goalkeeper, they can always say goodbye to Ulreich quickly.
