I'm thinking me might be the odd man out at the start of the season and even more so when everyone is fit.
I can see flick going with.
Olmo
Gundogan
Yamal
Christensen
Casado
To start the season, or maybe I'll drop gundogan back for Casado to have experience players in the starting XI, in which case he will start.
But once Gavi, pedri and De Jong gets back, he will have to fight for a place in the starting, I can see him getting good minutes, but across the 3 behind lewa and not nailing down any specific starting position.
Another bonus of signing Olmo, that one signing means there will be more competition for starting places, which can only be a good thing.
