Poor according to who? On whoscored he is 3rd in rating after MATS and Griezman.
In general, Dembele critics recently tend to just drop a 'he was poor' comment without any elaboration or any proper evaluation of what he did in each game.
All of what you say are criticism mounted against him in the past, some of them were valid, but we are seeing less and less of it with every passing year.
Yesterday in particular I did not see any poor decision making or lack of composure.
He failed to convert a couple of chances (which again he himself created with his moves), which on other games he had converted (or he had converted more difficult ones).
And if you weigh that against what he provides, there is no discussion really...
The way he generates chance after chance out of nothing is remarkable.
PS: I don't know what exactly the 'defense of Vini' in RM forums is, but I find also the criticism against him unfair. He is very young and has tremendous quality, he can learn how to finish better and explode as a player.
Did you watched the game yesterday?You really think Griezzyboy and Dembouz were better than De Jong for example?Football it's not only stats.
