Nunez takes shots from basically anywhere tho while I have rarely seen Jackson attempt to score from outside the box
Personally, I doubt Jackson will ever be super clinical. He just does not have it in him . The intuition, the decisiveness, that little bit of arrogance. Does not mean he can not hit a golden season once or twice in his career.
But that is a problem many strikers nowadays have. They are asked to do everything. Run the channels, link up play, hold the ball up, and park defensively. Jackson has his uses with his pace and work rate. Ppl like him less than Werner despite being a similar player. But his attitude is often horrific in contrast to humble Timo. Morata was probably more talented than both but all three have recorded some of the worst misses in history. Attitude surely plays a huge role here.
anyway, as many on here have said, Jackson is not the problem per se , it is that he is asked to be the main man which he clearly is not capable of being.
