Manchester United boss Sir Alex Ferguson has set striker Wayne Rooney a target for 40 goals for the season after his double against West Bromwich Albion sent his side top of the Premier league.

Rooney's two goals took him to 26 for the season, and 20 in the Premier League, but his manager is demanding more between now and the end of the season.

Ferguson wants Rooney to hit the heights of Dennis Law, Ruud van Nistelrooy and Cristiano Ronaldo, reaching the 40 mark for a season and leading United to another league title.

"If he gets to 40, I’ll be absolutely delighted because we’ll be in business then. He’s on a hot streak and he does these things," Ferguson said.

"His first goal was fantastic. I thought he would’ve been offside because it was so clear but when you see the timing of his run, it was fantastic and a really good finish.”

The 26-year-old's current highest tally is 34, achieved in the 2009/10 season, which saw injury problems blight the end of his campaign.

But instead of joining the select group of three United greats, the England forward is only concentrating on helping his side towards their 13th Premier League title.

"I'm sure we all would! I'm playing well and scoring goals so I hope that continues to help the team," Rooney added.

"To be honest, I obviously know what my [previous best] tally is and how many goals I still need to score to reach it. But I'm not focusing on that at the minute.

"I'm focused on the 10 games left and hopefully getting those points to help us be successful. If it happens, then great but the most important thing is for us to be winning trophies."

The goals against West Brom was the seventh time Rooney has scored two in a game this season, along with his two hat-tricks against Arsenal and Bolton Wanderers.

Rooney has a maximum 15 games to score the extra 14 he needs to appease his manager, with his first opportunity coming this Thursday as United attempt to dig themselves out of a hole against Athletic Bilbao in the Europa League.
