Too early to say that as Koop has only played a few games, for example.
If you want Haaland or Mbappe perhaps then I've got news for you.
I think Chico and Nico are both capable of changing games, but only time will show that. Yildiz is supposed to be but it's not coming together atm. DL also being a meme at this stage doesn't help, but I'm not one of those trying to change players every transfer window, so maybe not the best for this discussion. Some of us are old enough to remember big players being in really strong teams who fans were calling flops after the first 3, 6, 9 months, etc.
