I feel people are too obsessed with age. I dont see any physical decline with Matic and he is 31. He still has like 2 good seasons in him. He wasnt particularly plagued with injuried nor can you tell he is physically declining, its just that we were a mess tactically for a long time. All of our midfielders looked bad.
Now that we finally seem to have a good thing going we look good again.
Also I think forcing McTominay or Fred to be players like Matic just isnt going to work. Theyre not that, theyre box to box. Can they learn, McTominay especially? Perhaps. Not counting on it though.
Replacing Matic isnt an immediate concern for next season but if we can find a young player or two who play the right style just like Matic I would be down for that. We dont necessarily need to spend big. Get a Daniel James or two for that position.
