Do you have inside info that says Tuchel wants a ST more than anything?
Am sure the club have tried or are trying to sign a big-name ST but at this point, it's hard to tell what exactly are they doing. I mean, if we could afford the deal now, one would imagine we would have put in some sort of bid by now. The club could obviously be negotiating quietly and all that but based on recent reports, there doesn't seem to be any inkling that that's happening. If we're relying on selling players to raise funds, then we certainly haven't raised enough and it doesn't look like we'll have enough time to raise funds to throw in a bid before the "deadline". For all we know, the club might have moved on and quietly trying to sign someone else while the media, who don't know have a clue, are just recycling old stories to get clicks, a bit like how the Kounde deal has come out of nowhere.
As for what City and United are doing, like the others have mentioned, don't think getting Grealish improves City a great deal. He's just similar to/like every other attacker they already have in their team. United may have signed Varane and Sancho but if our last season is anything to go by, then people should know that it doesn't mean that will translate to immediate improvement, especially when the manager is not at the highest level.
