Sims is decent at going forwards, but his positioning and defense are not good. Elyounoussi seems to be good with his positioning and defense, but not going forward. If we bring in a two attackers it is difficult to see other getting much playing time.
Oh, and Sims was worse than Elyounoussi. Way worse. You guys look at when Sims does something exciting and then forget when he's not there. Then you hyper-focus on Elyounoussi every second his is on the pitch and nitpick everytime millisecond he does not score.
Not to come down hard on Sims because of course he needs time to develop. But after an initially promising start, when he was given lots of pitch time it was pretty obvious he is not PL quality right now. He's really fast so you have to keep half an eye on him. Pretty much once you do that, he can't hurt you. And he always wants to run past everyone so he is negligent in his support duties. I don't think he is selfish, just too excited and not aware if how quickly teans can react and counter. But anyway, yeah he's really bad right now.
