If Aguero was at odds or incompatible with the way Pep wants to play, as was being suggested earlier in the season, then he would most likely have gone.
The fact that everybody concerned has already said he's not going & now the chairman has repeated it, should allow us to finally stop talking bollocks about it & get on with the real world.
There is no reason a young striker should signal the end of Aguero, any more than B Silva signals the end of D Silva. They are in the latter stages of their City careers so each season will face a tougher fight to stay at the required level whilst a young striker increases in stature.
If we had fucked off Aguero & found G Jesus didn't get off to the same level next season, wewould look a right bunch of silly ****s, irrespective of whether we sighned Mbappe
(who is fuck all like Aguero).
