Seems to be awareness rather than brute strength to me. One of his better moments of the game was a nice little turn / feint to get past one player, and then just dallied on it until a Chelsea player caught up with him and took it off him.
A few times Xavi was faced up against a defender one on one and just sort of ran into them unsuccessfully attempting a skill. And then that pass back to VDV for their goal, if in doubt trust the touch of your teammate and put a bit more on it. Granted Mickey carried on the shambles but was dragged into a less than ideal situation.
Yesterday was an awkward one, Frank seemed to be doing him a favour by leaving him out from the start, but then the plan changed after Bergvall's head injury / substitute for concussion protocol. It's definitely not for a lack of effort but then very little is coming off for him so it looks like he's trying too hard if anything.
Everyone bar Vic played badly so it's unreasonable to single him out but at the same time, we've seen the other players do well at times. I'm not sure about this idea of not being able to judge players because they're new / young / adapting to a new league, as said it's a big ask to hit the ground running but the present matters and we could do with even just one of our high potential attacking players stepping up in the here and now. Madders and Kulu have been out for a while and will inevitably take time to get up to speed.
