The 26-year-old failed to find the net during his first six games for the Red Devils this season.
After registering his first two club goals of the season in today's 4-2 win over Stoke City, Rooney said: "I've worked hard for those goals today. Getting the goals for England helped."
Rooney's afternoon had earlier got off to a less than enjoyable start when he opened the scoring at Old Trafford by heading into his own net.
On his own goal, he added: "I was marking Ryan Shawcross and I couldn't see the ball so it came and hit me and went in. It was important for me to move on and not let it affect me and I did that."
Prior to today, Rooney had never scored an own goal.
