I think so. I keep seeing people in match threads say play our best players every game. We're going to pay for it. In my view, we should have rested more players here. It's quite clear that ETH doesn't like to rest players very often. I just don't think it's a good idea to play the same players every 3 days. If we can't rotate against a Championship team at home, then it's impossible to do so in practically any other game.
Bruno, Rashford, Casemiro, and Eriksen play every game. Antony plays a lot, too. He does seem willing to rest Varane.
If he doesn't rotate against Forest when we're 3-0 up and playing at home, that'll be ridiculous.
