Welbeck has greatly improved his physical aspect of the game; he has gone from looking slightly sluggish to becoming very, very fast. He is very strong, great technique, but his decision making and end-product aren't yet good enough.
It's a bit annoying that many think we should write him off because he hasn't made the full breakthrough yet. He's 21, playing for England and a rotation player for United. Recently he is playing on the wing, which clearly isn't his favoured position. However, he will develop there as we already see. Now he is much more able to carry the ball at pace; against QPR he dribbled past and outpaced his fullback, he can cross and cut into the box. Sadly, his end-product leaves many of his runs seem a bit pointless, but he will get there.
He can be a bit frustrating at times, but he is still very young; to say that he lacks talent is ridiculous. He can, and hopefully will, become a great player for us. Ferguson said that when he turns 24 he will be a class striker. I believe that!
