The only thing I can agree with you on is that Gueye is superb in the middle of the park, Kante esque. But Barry puts in so much nitty gritty too.
Williams is fantastic for them in my opinion, and one of the main reasons how Wales progressed so far in the Euro's, and I know you're going to post some heatwave map or some nonsense like that but leave it out lol, football is so much more than just statistics.
Bolasie has super pace & trickery, and if he becomes more consistent, can be one of the best "I'll take you on and beat you" wingers in the league. I do know what you're saying about Delofeu, but I don't think he would *overly* improve the team, Mirallas, barring his selfishness, pretty much brings everything Gerard would to the table.
