Can't deny that output looks good, but may it also be noted that (assuming those figures are correct) we paid £300k a week for 13 goals & 5 assists in the PL from Raz.
On the other hand the 31 goals & 17 assists from the other 4 players cost us £372k per week, total.
It should be noted Raz achieved his figures in 2127 mins of football, compared to the 8147 total mins by the other 4. So whilst Raz achieved better numbers than the others, he did it with slightly more time on the pitch than the others (on average) and those numbers cost us a darn sight higher premium.
Granted Foden will likely get another £100k per week if he signs a new contract, but you can see why there's an expectation put on Raz, financially, that he just isn't quite meeting. The player of a couple of seasons ago would be worth every penny.
Don't think for a second the stats guys at the club haven't weighed up these same numbers and offered Raz a deal they think is reasonable. If we can get £50-60m for him I'd say it's fantastic business.
