The 27-year old striker scored twice as United opened their European account for the 2013/14 campaign, notching up his 200th club goal in the process.
But Rooney preferred to revel in the victory with his teammates rather than go on about his individual accolade.
"I'm really proud, to first of all to be playing and to score and it's a good result," he told ITV.
"Obviously the first game in the Champions League is always important and thankfully we got the victory."
And Rooney was quick to deflect any questions about his desire to leave Old Trafford in the summer when quizzed on the issue.
"I've concentrated on working hard to get my head down to get myself fit and ready for the season," he straight-batted.
"I'm delighted with the way I've come back and delighted I'm back playing and scoring goals.
"The fans have been brilliant, they have been fantastic with me. It's great the reception I get here and hopefully I can replay them with performances and goals like tonight."
