Romelu Lukaku is at it again.The burly Belgian forward opened the scoring for Manchester United against CSKA Moscow on Wednesday with his ninth goal in nine games and his second strikes in two Champions League outings.After Zlatan Ibrahimovic hit 28 goals last season, many United fans were worried that the club would struggle to replace his goals this term following his serious knee injury.Especially after the club moved on all-time record goalscorer Wayne Rooney, too.However, the former Everton man has settled in perfectly after his £75 million move this summer and his powerful header from an Anthony Martial cross against CSKA sums up his influence on the Red Devils.In spite of his goal scoring exploits, much of the media attention has fallen on the song the United fans sing about Lukaku rather than his form.The song contains suggestive lyrics about Lukaku's penis and it has been suggested that the chant encourages racial stereotypes.Following his goal in Russia on Wednesday, BT Sport presenter Gary Lineker couldn't help but fire a well-timed pun. Since his tweet, Lukaku has extended United's lead to 3-0 with his second following a Martial effort.

Mino Raiola, Lukaku’s agent, told The Times two weeks ago: “He would like this song to stop. They are talking more about the song than about his football. That’s his and my quote.”

But a small minority of United fans ignored Lukaku’s request when they faced Southampton last weekend.

United subsequently released a statement in which they said the club had asked for CCTV footage from Southampton and threatened to take action against the guilty culprits.

“The club and player have been clear in asking for an end to the chant,” the statement read.

“The club has worked with relevant bodies and supporters’ groups in trying to eradicate any offensive behaviour and will take further action against individuals if this continues."

Lukaku has surely answered the questions that hung over the 24-year-old and whether he was able to cope with leading the line for a major club.

After failing to make the grade under Jose Mourinho earlier in his career at Chelsea, it seems they have reunited at just the right time.
