It's interesting how interpretation works; for me, it further suggested he was startled and in shock (or shell shocked) and not with it for the duration of being blitzed, freezing, being dispossesed and then watching his "assailant" run off with the goods (ball). A bit like someone being robbed on the street. Shocked and temporarily frozen, not lazy or indifferent, just lost for a moment.
This happens when your senses get overwhelmed - being startled like that can be the result of sensory overload and it's not the first time it's happened to him over the last few games, but it is the worst example as he looked totally out of it rather than being able to try and make a recovery play.
The run on here is saying he should be the first name on our teamsheet for midfield. You are seriously saying he is outperforming Casemiro and/or Bruno in deep midfield?
Think you might be in for shock there; getting in a new, quality CM or DM, the preference will be slot him next to the best player and not only share the load, but have perhaps a greater responsibility than his partner to do the heavy lifting - I think that would reduce Ugarte's purpose, not enhance it.
We're using a 2-man base, not a 3-man midfield with a runner who can go and track the ball. The priorities are different then and I'm surprised you think a quality midfielder wouldn't be used to aid one of the other guys than they would be to aid Ugarte in doing his thing. What I'm saying here is his thing wouldn't be catered to and he'd become even more the target for the opposition to focus on. At least with 'old man' Casemiro or 'defensively irresponsible' Bruno, there's potentially change to be had out of them in terms of stamina and mobility (Casemiro) or positional indiscipline and erraticism (Bruno); if we actually got our midfield in order, Ugarte would immediately find himself on the wrong side of it in another PSG scenario where he, in isolation, doesn't offer enough to justify his position, but also for him to then become the sole focus of opposition planning (drawing fouls, overturning the ball, being made to play faster than he can cope with, being the pressing trigger point) none of that improves for him in a better midfield, it just highlights his own shortcomings even more. At least right now he is an engine and the legs, but better midfields ask for far more than that from a player.
By asking for what you are, you're essentially having him phased out of the team before the other two.
