It is a difference but the way it was worded sounded like it was dissing his first touch a bit didn't it?
Hernandez has a great touch when it comes to setting himself up to put the ball in the net. That goal against Valencia in the CL group stage last year was a great example of that. I think he's also looked sharper in his link up play this year too, obviously not brilliant or anything but still improved, so he's obviously worked on it.
Obviously Welbeck will likely become a better all round forward, but I can't see him becoming as good a goal scorer as Hernandez, which is why it's a good thing to have both in the team isn't it?
At the end of the day though, they'll likely be picked based on who compliments Rooney better, and that's still Hernandez for me, though Welbeck has shown he can link up well with him too, so who knows.
