Would be interesting to see what happens firstly with Grealish going to City, while not a done deal yet, seems like that one is on the cards more. Perhaps a Sterling or Mahrez or Silva would be heading out the door and there is no doubting the impact Grealish can have on a game, seeing what he has done for Villa and also with England in smaller amounts over the summer, however with Villa he was the main man where pretty much everything went through him, at City he wont be so it will be a slightly different role he plays for them but no doubt will fit in, he just seems to have the movement and quick turns that defenders can not cope with. While it may not make City a better team as such its deffinately a different type of player that will cause different problems for opponents so gives them more options.
Kane saga has gone extremely quiet other than Spurs higher ups saying he is theirs and not going anywhere so you have to believe thats the case for now. City spending £250+ would not really be a thing to them (not matter what guff they might say about having no money/dont spend a lot on one player blah blah blah) but it would certainly be a statement if they got both this summer and suddenly our business would look less impressive but then its all relative.
A lot of fantasy teams are waiting on the outcomes of these moves you feel.
