The Dutchman hasn’t scored in eight games now and despite having a fruitful international break with three goals and three assists in two appearances for Holland, he couldn’t find the net in subsequent games against Sunderland or Chelsea.
And his fitness is going to be monitored closely ahead of the last eight games of the season for United that could see them win a 20th Premier League title.
Speaking to Inside United, Ferguson said: “I’ve no worries about Rooney because he’s needing games, he’s the kind of player who has to play all the time.
“With van Persie, we have to monitor it because we still don’t know all about Robin, and the kind of seasons he’s had.
“I don’t think he had a season of such intensity during his time at Arsenal, so we’ll have to look at that. Welbeck’s looking strong as well, as is Chicharito.”
Despite claiming to be in the best condition of his life at United, van Persie has certainly looked sluggish in recent months in comparison to the player who ripped the Premier League apart in the first half of the season.
And with Rooney, Hernandez and Welbeck all vying for the same spot, Ferguson certainly faces a selection headache ahead of Monday’s clash against Manchester City at Old Trafford in a game he knows everybody wants to play in.
“These are the games that everyone wants to be involved in, the derby games,” he continued.
“Over the last few years the derby games have been far more important than they ever were, so we’ve all been looking forward to them.
But we’ve had a heavy programme leading up to the game so we just have to manage it.”
Victory on Monday would all but guarantee that the borrowed trophy sitting in Manchester City’s trophy cupboard would be returned to Old Trafford where it belongs.
United have lost a spark since the Real Madrid controversy but beating City in the first derby at Old Trafford since that game will give the squad a massive boost, something it looks like they need.
