The striker has shared his joy in joining a select few of Manchester United legends, and thanked fans for their support ahead of Sunday's derby clash against Manchester City
The England international netted a double either side of a Robin van Persie strike to secure an opening group game victory in his 406th outing for the Premier League champions.
Rooney insists his primary focus continues to be helping United win matches, but is quite proud of reaching a target attained by only a select few at Old Trafford.

|6/1||Wayne Rooney is 6/1 with Coral to opening the scoring v Manchester City
"When you look at the list of top scorers I think I’m only the fourth player in the club’s history to have reached this number after Sir Bobby Charlton, Denis Law and Jack Rowley. It’s certainly something I’m very proud of.
"My main aim is always to help the team win games and if I score that’s a bonus. Hopefully there are still a few more goals to come from me yet."
Rooney, who was the subject of summer-long interest from Chelsea after submitting a second transfer request in under three years, went on to praise the United fans as he shifts his gaze to Sunday's derby clash with Manchester City.
"The reception I got when I was substituted was amazing and meant a lot so I want to thank the fans for that," he continued.
"The Manchester United fans have been brilliant since the start of the season, their support home and away is always top drawer and means a lot to the team.
"The best way to repay the fans is with good team performances. I’m happy to be in a position where I get the opportunity to score goals – and long may that continue.
"My main focus now is preparing as well as possible for the game against City at the weekend. We all know they are a strong outfit and have made some good signings over the summer so we will definitely need to be at our best come Sunday."
