Its fashionable to dislike Doku and he obviously has a lot of flaws in his game but people forget easily.
First of all, he made an excellent assist today.
But there is also last season. He tormented TAA and Liverpool, and Carvajal and Madrid, carried the team in the FA cup final against Man Utd and in the semis against Chelsea, and pretty much saved the title by breaking Porro against Tottenham. There was a bunch of other matches where he made plenty of impact. Since arriving he has more G+A than guys like Garnacho and Madueke. Became the youngest player ever to have five contributions in one match. No easy feat for someone in his first season.
Theres a reason why he was so highly rated as a youngster, and super knowledgeable people from Klopp to Henry to Guardiola raved about his ability. FFS even Mbappe has said he was in awe of Doku. He is low on confidence right now and isn't put in a position to make an impact. But hes still super young and absolutely on the track to stardom if you use and develop him in the right way.
Just stop letting him muscle up so much lol, hes losing his best feature which is his acceleration
