You dont score 20+ league goals in a season without having a strikers instinct. When that ball is in and around the box, are you seriously telling me he doesnt get that strikers instinct and knows exactly what to do? I didnt see any out and out strikers outscoring him in the league last year.
Thierry Henry was always a left winger just like Depay, but he also had the ability to play as a striker, and Wenger noticed that. LVG has probably noticed this in Depay aswell.
As for my comment, i meant that if it was that easy to score goals from the left wing position then wouldnt more of the worlds top wingers be scoring close to that ammount? The answer is no, because they dont have the strikers instinct that Depay has. Do wingers not know how to exploit defenders? Attack space? Of course they can. And his goal tally proves he knows how to put the ball in the net. He outscored every single "striker" in the league last season, but he cant play as one?
Just because he doesnt start out as a striker on the little graphic line-up before a game doesnt mean he doesnt take up a strikers position in-play when he doesnt have the ball. If you have watched his games like you say you have then you know full well he doesnt stand on the left wing for 90 minutes. He's constantly in and around the box just like a striker would be. He's been making the runs and scoring the goals all season.
