Manchester United's Robin van Persie has backed the Football Association's decision not to charge him over an alleged elbow on Newcastle's Yohan Cabaye.
Newcastle manager Alan Pardew was angered by the incident that took place during United's 3-0 away win on Sunday and called for action to be taken.
However, the FA decided to take it no further after referee Howard Webb reviewed footage of the incident and said he did not consider it to have been violent conduct.
Asked about the FA's decision, Van Persie told voetbal.nl: "I agree with the union."
The former Arsenal striker has hit the ground running since joining United in the summer and is currently enjoying every minute of life at Old Trafford.
"It's fun and it's going well," added van Persie. "It is a great challenge. I will have to change a bit, but that happens in life often enough."
Meanwhile, Darren Fletcher has urged United boss Sir Alex Ferguson to give him the chance to prove he is ready to become a first-team regular again.
The Scotland international, who was diagnosed with a chronic bowel condition last year, has completed 90 minutes in both the Capital One Cup and the Champions League, but is yet to be given the nod in the Premier League.
Fletcher has linked up with his international team-mates ahead of Scotland's World Cup qualifiers against Wales and Belgium, and he believes he is back to full fitness and is desperate for the opportunity to make his first league outing since last November.
"I know the manager has got such a big squad now, especially in the midfield area, and there is a lot of competition for places," Fletcher told MUTV. "I have to be patient and wait for my chances but, hopefully, one will come around sooner rather than later.
"I think my general fitness is fine, it's just match fitness - the sharpness, reaction times, things in your head and things like that. The positional sense, when you're a little bit older, comes back to you fairly quickly.
"To get as many 90 minutes as possible is great just now. After not playing for a long time, it's important to get games back into your legs. Fortunately, I've had quite a few games for the reserves as well."
