Daz the squad rotation story is the biggest misinformation on this forum. People love bringing it up. There is no way this team is top of the table if we keep spotting in Jolding, Nketiah, Bieira at the same time. The team has had some injuries that force you into making 1 or 2 changes anyway, which just about retains the individual quality, relationships and automatisms. You start constantly taking people in and out, and the quick flowing, press-breaking football falls apart.
You need to do things in stages. You build the base. And then you keep layering new, high quality players in. Otherwise you end up losing individual battles all over the pitch each week, and that weakens the entire team.
Go look at how many minutes fringe players like Nketiah and Vieira have played, and then go back and read the discussions here each time these guys were on. They depleted quality.
Our best bet for rotating us to go add players like Rice and Caicedo this summer. Not to rely on Elneny.
