Tbh I don't think Rom was actually bad last night either. He was wasteful, perhaps, but so were Ross and Kev to an extent.
But the tactics were right RFUS. We played it perfectly. You can't go all out when you have Jagielka, Williams and Barry at the back who lack the pace to recover, especially with the pace of Rashford and the general all-round bossness of Zlatan. We threatened on the counter and we actually had several really good chances to go and get a second (Ross's cross, Rom's cross to Kev, Barry header - just a few examples from the second-half).
We take those chances and - actually even as the pundits said(!) - that game is well won. We need to learn to take those chances. It wasn't like the City game where we literally had one chance and scored it.
The squad is threadbare but tbh I'd rather it be the kids getting a go than the tosh of the last two seasons. That being said, the last 10 minutes was not the time or place for DCL and we had a player there in Valencia who could well have helped us see it out.
