From what I’ve seen, Eisa is quick with a cracking shot and Gillead is slower with a good range of passing: based on that, both could well shine in their “new” positions, given a bit of time. But I could be wrong, so could Cox.
I would just ask why Cov is doing this, does he feel that moving these players will help make up for shortfalls in other areas of the squad? We all know we’re short of midfielders and none of the fit strikers are particularly quick.
But if it doesn’t work, I’m sure Cox will shuffle the deck again in a couple of games, you just have to give these things a bit of a chance.
