Oh I would say that they are easily better than us. Unlike many on here, I still like and rate Ron as a manager - but I don't think he's doing anything special there. 7th is the bare minimum they should be getting. He'll be fine achieving that this year, and probably next year too. But unless he adds cup wins/finals to that, it'll soon not be enough.
In my view, Williams would get into our team alongside Virgil; Coleman would just about get in ahead of Cedric, albeit not for much longer if Cedric continues his progression over the past year; at least one of Morgan and Gueye would walk into our midfield, and there's a case for saying that the other would get in ahead of Romeu (even though Romeu has been brilliant for us - Sanchez is a great player, but Messi is still better); Barkley offers them that central link between midfield and attack that we badly lack (goals and assists, in and out of the box); and just all-round they offer a threat across their attacking line - even with Bolasie injured, they can still loan Deulofeu out and often leave Mirallas (who I greatly rate, above Tadic and Redmond) on the bench. And yes, that does obviously include Lukaku: he might be too good for them etc, but he can't just be shifted to one side when comparing the two teams. He is an Everton player. The hope I guess from our point of view is that Gabbiadini can ultimately prove himself to be equally of good (although unlike Lukaku and Everton, the downside to that is that it would just lead to us selling him).
Flip it around: Virgil and Bertrand would walk into their team, absolutely no question in my view. But anyone else? I'm struggling. Forster in previous years yes, but he's not been great this season.
