I don't know how you can be so sure about it. All they have to do is improve slightly and they're in the mix for 7th, which is about what their fans could hope for.
Their manager is washed up and couldn't do it in the Chinese league, id question his hunger for it at this stage of his career, we ''weren't impressed'' when we interviewed him in 2016.
Couple of players could be good, they signed a RB on a free from Fulham. Yarmolenko is on a decline in his career, had a bad time at Dortmund and ended up at west ham. Wilshere I actually like, but if he's hit with injuries etc etc.
That diop has arrived with a decent reputation, but we'll see how he gets on in a different, more physical league (nobody else bid I don't think). Think they'll finish between 9th-11th
As we found out last summer a lot of signings at once doesn't work very often, I think we'll see an improvement from them but don't think they'll be troubling many teams
