Manchester United manager Sir Alex Ferguson feels Wayne Rooney can match Cristiano Ronaldo's record of 42 goals in a season after seeing the in-form striker bag a double in the 3-0 win over Fulham. The Cottagers held United out during a goalless first half but Rooney slotted home from Nani's pass less than 30 seconds after the break before racking up his 32nd goal of the season with six minutes remaining. Dimitar Berbatov made sure of the points by heading in Park Ji-sung's excellent cross as the Red Devils went back to the top of the Barclays Premier League. Ferguson told Sky Sports News: "I said a while ago it's impossible for a player to get 42 but he is on 32 and there is a challenge there for him. "He is capable of scoring in the next eight league games and five possible European games, so he has 13 possible games and you never know, I wouldn't put it beyond him. I was just glad he got to the 30 mark, but we are enjoying his goalscoring." But Ferguson admitted the visitors had made life difficult for his side. "I think Fulham with their possession made us work hard and chase around a bit. It was hard to get the ball off them. They have experienced players who are comfortable on the ball. "We had to try and increase the pace of the game and hurry them up a bit, but the most important thing about that start (Rooney's first goal) was it put their team on the back foot and gave us momentum." Ferguson was also pleased by the margin of his side's victory given the tight nature of the title race. "You have to think about goal difference. We are only four goals ahead of Chelsea, I wish it was 14 to be honest, but at least it is in our advantage." Will Rooney reach 42 goals this season? Have your say.
