As an attacker I do think he’s overrated a bit. He’s dangerous and direct but his end product in creating goals for himself or others isn’t as good as it should be. Perhaps in a better side with great attackers he will blossom but I do get your point.
What makes a 50m+ player is harder to see. He’s very responsible and effective defensively for a winger and he has a big heart. Despite the flaws in his game he’s gonna run through a wall for his team and give everything. That has a lot of appeal. He’s not a great player at this point, I agree, but he can be vary valuable to a club in terms of decent production, defensive contribution, versatility, spirit.
