Grealish definitely only loves Villa and will do his best to ensure the club is in the best position it can be.
I think a lot of what you say is hope fueled, which is fair enough, as that's how we all end up taking information when it comes to our respective clubs.
Villa are building a good squad but to challenge for what? Domestic cups, a europa league place perhaps. It's not quite league titles and CL success, which is what all top players want.
I think Villa could do a lot with £100m to help them challenge domestically. The fans will have lost a huge player but if the club can get two or three big signings with the cash then you'll have more weapons in your arsenal.
We shall see how it plays out. It is City or Villa from the current paper talk. It's good to have fans from other clubs on here, even if you might get a lot of shite from some. Stick in there. We welcome most fans other than rags and dippers! Directly linked to the shite they chat.
