concentrate on working hard under "great manager" David Moyes at Manchester United.
The England striker was reportedly keen to leave Old Trafford for Chelsea during before the transfer window shut, but having been denied a move he is now intent on writing his name in the club's history books.
"I've put my head down and worked hard and tried to do everything right," he told the Daily Mirror.

"I feel good. I've had some good training the last few weeks. It's been stop-start with the injuries, but I've just kept my head down and worked hard and now I've played and got some goals."
Despite question marks over his relationship with new boss David Moyes, the 27-year-old insists he is delighted to be reunited with his former Everton boss and claims he is relishing the Scot's methods on the training ground.
"I feel great," he insisted. "The training is a bit different under the new manager - I remember it from Everton, it's more intense. That's helping me. I feel good and am glad to be out playing.
"He's a great manager and thoroughly deserves this job because of what he did at Everton. It's good to work under him and hopefully be successful together."
The 27-year-old was also keen to dispel rumours of any bad blood between him and striker partner Robin van Persie, revealing he enjoys playing alongside the Dutchman more than former team-mate Cristiano Ronaldo.
"I've seen things said over the summer, but me and Robin are friends off the pitch," he continued. "There's no problem between me and Robin at all. We're great friends and we want to help each other and be successful.
"I think the manager has made it clear that he wants one up and one behind, and whatever way round that is it doesn't matter to me.
"It doesn't matter as long as one is always filling in behind and helping out the midfield.
"We've done the work together and the times we played together last season we did well, so hopefully we can play more together this season and do well.
"It's different [to playing with Cristiano Ronaldo]. Ronaldo played out wide most games and I was on the other side, out wide. We were both playing off the front man.
"This is different with Robin. We dovetail well and try and help each other score goals."
Having become just the fourth player in Manchester United history to reach 200 goals with two strikes against Bayer Leverkusen, Rooney admits Moyes has now encouraged him to surpass all-time leading scorer Bobby Charlton’s record of 249 goals.
"Obviously those conversations are private, but I knew it anyway,” Rooney explained.
"It's always a challenge. It's a massive football club and it's amazing how long that record has stood for.
"So it's great to get to 200 goals. That's a great honour and I'm really proud of that. To be edging closer to it [Charlton's record] is great for me.
"But I think the most important thing for me was to get back playing and get among the goals and hopefully that will put me in good stead for coming games."
