I'd have it at 22 for the first three. 9.5 Jack - I'm not sure you could find any one else to be as creative and influential, and 6.5 AEG for his goals output.
I'd have the other three at 23.5. Ings at 8 and Bailey at 7.5. Hopefully he is more an 8.5 but hasn't played in PL yet.
So I'd have it closer, but marginally better off with new players. However the main point is how much stronger we are now than we were when Grealish was out injured.
It was the case throughout the pitch last season. The first team player was top half premier league level, and the back up was championship level.
