David Beckham: 'On fire' Manchester United star Wayne Rooney is 'world's best goalscorer'

AC Milan veteran David Beckham was impressed by Wayne Rooney's display in Manchester United's 3-2 win in the San Siro on Tuesday night.

The England striker scored twice and proved a real handful for the Rossoneri defence.

Beckham feels that the ex-Everton man is now beginning to justify so much of the hyoe he has generated over the years.

"He is on fire," said the Milan midfielder, according to Press Association Sport.

"I have always said he was one of the best goalscorers in the world and he is proving it week in and week out.

"If you give him chances he'll score goals, that's the way he is and the way his mind works."

Beckham is also backing United skipper Rio Ferdinand to do a fine job as England captain after taking over from John Terry in the wake of the tabloid scandal involving the Chelsea defender.

"Rio is a great captain," he added.

"He has proved he has been a great captain when he has captained Manchester United in the past. He is a leader."

Meanwhile, Beckham admitted that playing against his former club had been strange, but he was looking forward to March 10's second leg at Old Trafford.

"Obviously it was emotional," he stated.

"It is the first time I have played against United since I left and I have to say thank you to the United fans because they were incredible, singing my name and things like that.

"It was an emotional game for me. To play against the team I started my career with is obviously a big thing, but I enjoyed it.

"Losing the game is disappointing, but the second goal has given us a chance."
