They don't need to be good enough to break into the team, just good enough to get on the pitch here and there.
We have had scores of them good enough to do that in the past few years. We could play all of them for the next 3 games if we wanted to.
We are choosing not to play all of them. Nothing stopping us from playing some of them.
Now and next season.
Foden 1 appearance away from becoming the youngest (and only 17 year old) PL medal winner in history...puts some perspective on how much playing time he's getting.
