I really don't understand people who criticize Doku, even if all players can be criticized. In fact, I don't understand players who belittle the player he is.
Do they realize how EXCEPTIONALLY easy he is to eliminate? Apart from Vinicius, no other player in the world has such an ability to eliminate and dribble. With this kind of player, you can make any team retreat, which is a considerable advantage. He's even effective against low blocks and can break the deadlock at any moment. He constantly monopolizes the attention of two or even three players, creating space for the others.
So, yes, he still has room for improvement in the final pass, but he's only 22. Why do you think Pep starts him every game?
