Tolisso is an extremely valuable player and should be given a chance if Thiago leaves. He was a beast before his injury but has been mainly a sub every since due to the form of Thiago, Kimmich, and Goretzka.
Goretzka is amazing not just because he has been in the gym but because he still kept his pace and agility while building better which helps him ingame as well he is more all-rounded than tolisso and at the moment the better option for the offensive CDM role.
Muller its more important for Bayern attack and in his good days he can decide games nearly alone. Muller is not the Bayern is way more complete with stars in every position, therefor the intelligence and skills of anyone player go unnoticed. Wheras kdb is way in control if midfield and creating, as he is their best player. Also he is flashier, and muller intelligence, like his brilliant one-touch pass to set kimmich up for the assist in finals, is not talked about.
Neuer ever since the one season after his injury when he was off, he’s been super underrated. This year he proved he’s still the best so many people for some bizarre reason think Neuer isn’t the best and it confuses the hell outta me.
If Gnabry continues the way he's playing he might end up having a better career than Arjen robben. He is also less injury-prone. If he continues working then yes, there are great things ahead for him. Boateng's long passes are some of the best out of all defenders.
