Against a bad team that is in a relegation battle that we were completely dominating? It was one of the safest lead we've had in months, and if we can't trust the team to hold on in that situation we'll never be able to. It's actually worth noting that the only other two 'safe' leads we've had (Betis and Leicester) ETH did sub Rashford off so this is the first time I've felt he got it wrong. Unfortunately we then just got extremely unlucky that it actually cost us.
It's not like I'm here saying that ETH utterly fecked up and it's all his fault. Nine times out of ten nothing bad would have come out of it. But I do think there are a couple of players in our squad that we need to protect to some extent when the time is right (Varane being rested in this match was a great example), and Rashford is the one who we get the least opportunities to rest so we've got to try to take them when they come about.
Varane, Shaw, Martial, Eriksen and Rashford are the five players that I think we have to be careful with to differing extents. I feel ETH has done very well with the first two, Martial has been injured so much that his rotation hasn't been a factor at all, but that Eriksen had been overplayed before his injury and his performances had dropped off significantly, and that Rashford has been that important we've barely been able to rotate him at all.
