He hasnt had a real pre-season due to the summer long groin injury.
Create chances for him, then complain if he fails.
Until then zip it, you dont sign a poacher then starve him, let him go around games waiting for scraps and only thing out there for him is just physical duels since defenders can just fully focus on him without fear of much of a creativity around him. The longer this goes on, the more he goes into his own head and plays frustrated more and more, leading to defeatist attitude out there after while. Combination of this god awful set up being draining, and the pressure of being in his first top club, is not ideal for him right now.
We seen this movie before. The core issue is we dont create enough for him.
Thinking the solution is just dump him and we will be fine, when this dude could be placed in Bayern/most EPL top clubs and score 30+ goals without a sweat prolly.
