Age is not a big issue with Luis Diaz. He doesn't have many minutes in his legs. He'll be at the same level till he's 33/34 (He's 28 next season)
He doesn't have to be a scorer at Bayern if the system is set up to maximise Kane and Musiala's output.

If Newcastle don't wanna spend big on a GK, then they're gonna spend big on someone else. Sesko + some other BIG signing.
If Newcastle can really get Trubin next year, then fine.
