Manchester United ace Wayne Rooney feels he's improved his aerial ability this season.

Rooney struck twice with headers in victory at AC Milan last week.

He said: "Over the last few years I've worked a lot on getting in the six-yard box and now I'm getting in with my headers as well.

"I think I was always not too bad with the heading, but my timing was a bit out.

"I've managed to work a bit on that and I'm still working on pulling off defenders."
