Your last comment is a tad fanciful mate, let's at least see Gueye before we start saying he's improved the team!
Williams for Stones is a no brainer! But he's not even fit to play.
We go into the first game of the season a total shambles IMO, let's hope we can scrape a result.
I'd say for the way Koeman seemingly wants to play (high press) Gueye will be decent. Maybe a bit of a stretch I admit to say he's definitely improved, but overall we're I'd say as strong if not slightly stronger than how we finished last season.
That won't be good enough to push us on to the next level, though, so we definitely need reinforcements.
