Arsenal striker Robin Van Persie is hoping the two 'big games' against Chelsea in the Champions League affect Manchester United's Barclays Premier League run-in.
The Dutch international managed to shake off an injury picked up on international duty with Holland to face Blackburn Rovers at the weekend, but the Gunners' hitman was unable to break the visitors resistance in a frustrating 0-0 draw at the Emirates.
With Sir Alex Ferguson's side coming back to win 4-2 at West Ham United, the Red Devils are now in pole position to secure their 19th English league title with a seven point cushion at the top of the table.
Arsene Wenger's side have a game in hand though, and will also host United in a potentially defining clash on May 1st.
With two European quarter-final clashes against the Blues and an FA Cup semi-final match against rivals Manchester City to come before that date, Van Persie is hopeful that these matches will start to catch-up with their rivals.
"The way I look at it is that United have two extra big games before they have to play us," said the Holland star in reference to the Champions League ties.
"Hopefully, they will have to dig deep into their reserves and come here tired. That's how I am looking at it because I want us to have the biggest chance against them."
Performances will have to improve from the north London outfit if they are to stand a chance of claiming the title though, with Wenger critical of his side and their performance on late Saturday afternoon.
“Our rhythm of passing was too slow. It was exactly how we do not want to play. I’m really concerned about the level of our performance. We looked predictable.”
