The other way to put that is, as was already pointed out, last season Son, Betancur, and Bissouma had significant injury layoffs and a manager that effectively downed tools 1/3rd into the season. Hard to think that didn't effect players' form, including Kulu (and Richarlison).
Now we get a healthy Son, Betancur, Bissouma, a manager that gives a fuck. Add to that a keeper that isn't past it, one of England's best creative midfielders, anotger player with very high goal involvement/minutes stats on a free and counting.
Like I said, there's still world to do and it looks like the club is still working on a couple of defenders and possibly more. We're not nailed on top 4, aside from City who is? But acting like we're £300M away from top 4 is dramatic.
I'm more worried about the Postie than I am our transfer business.
