Sir Alex Ferguson insists Robin van Persie does not need a rest
Manchester United manager Sir Alex Ferguson has backed Robin van Persie to find his goalscoring form and insists the striker does not need a rest.
Van Persie, 29, has gone nine games without a goal for United.
But Ferguson is confident that the Netherlands international, who has hit 23 goals for the club this season, will soon start scoring again.
"He doesn't need a rest that's for sure, he's a strong lad with great physique," Ferguson said.
"The goals will come, all strikers have dry spells and you hope it ends quickly, it's part of being a striker."
Van Persie, who joined United from Arsenal for £24m last August, has scored 19 Premier League goals this season, second only to Liverpool's Luis Suarez, who has 22.
His last United goal came in the 2-0 Premier League win over Everton on 10 February.
The striker's shot led to the winning goal in United's 1-0 victory at Sunderland last Saturday, but it was recorded as a Titus Bramble own goal after flying in off the defender's knee.
Ferguson also confirmed that Wayne Rooney is back in training ahead of Monday's derby against Manchester City at Old Trafford.
The England striker, 27, has missed United's last two matches with a groin injury sustained on international duty.
Robin van Persie's goal trail
- Van Persie scored 23 times in his first 31 games in all competitions for Manchester United, including 11 goals in 11 matches between 28 November and 20 January.
- He has gone nine games without scoring for United - four in the Premier League, two in the Champions League and three in the FA Cup - since 10 February.
- But he has scored three times for Netherlands in World Cup qualifiers in the meantime - with a goal in the 3-0 win over Estonia on 22 March, and two more in the 4-0 victory over Romania four days later.
Brazilian full-back Rafael da Silva, who missed Monday's 1-0 FA Cup quarter-final replay defeat at Chelsea with a groin problem, has also returned to training.
Defenders Nemanja Vidic and Jonny Evans remain doubts with knocks picked up during at Sunderland, but Ferguson is hopeful that both will resume training soon.
He said: "Wayne and Rafa have started training which is good news. We hope they will be fine by Monday. Jonny Evans and Nemanja Vidic are not there yet but hopefully they will start tomorrow (Friday) or Saturday morning."
Premier League leaders United are 15 points ahead of second-placed City going into Monday's match.
Ferguson added: "It's a derby game with a difference from years ago. It's far more important. We have to get used to playing Manchester City in big games."
