That's fair enough and his stats on paper look good for a 20 year old. Taking his age out of the equation though, and bearing in mind 3 of those goals came in one game, he only has 2 goals in 20 games. We don't receive bonus goals or points for fielding a 20 year old. At the end of the day, he is a ludicrously poor finisher. On the other flank we have Navas, who hasn't scored for 50+ games. Those two are taking up two attacking positions on our pitch yet provide a very minimal goal threat.
If we are aspiring to be at the level of Real, Barca, Bayern etc, we can't be making allowances for such profligacy in front of goal, regardless of how old he is. The sheer amount of sitters missed by him this season is utterly mind blowing. I've never seen anything like it.
