We were three games from a quadruple without a striker last season. Aguero was already missing in truth. Grealish makes us better so we have done what we needed to and improved an already impressive squad.
Kane clearly answers a problem for us and gives us the option to play a variety of alternative systems. We can go long to him, cross to him or play a false 9. Torres could improve and fill that role more impressively or others could. Jesus might even knuckle down and deliver.
There is no 2nd option. Haaland isn't a goer and who else is there that has a CV as impressive as Kane's? For a club that has won nowt he has scored and created a shit tonne in so many different competitions for a sustained period. The club would be panic buying if they looked anywhere else.
Others might have improved too but we have added the most creative player in the league to our squad and are trying to add the top goal scorer too. That's a fucking statement of intent to everyone in England.
