The Netherlands international was happy to have struck both his side's goals against CFR Cluj on Tuesday night, and was full of praise for Wayne Rooney after his two assists
The Dutchman struck either side of half time to keep his side top of their group after Pantelis Kapetanos gave the hosts a shock early lead in Romania.
The Netherlands international has thus far proved to be worth every bit of the £24 million United paid Arsenal over the summer, with seven goals in his six appearances so far this season.
Van Persie, however, was keen to stress that he hopes there is still much more to come.
"I'm on the way," he told ITV. "I'd like to make more assists, as I've said many times, it's not only about goals. I'm on a good run, but it can always be better," he said.
"With seven goals I'm having a good start at my new club. But I only have one assist and that has to go better. A striker wants to win and score, but assist are part of the job as well. It's something I have to work on."
While he was fortunate to see his first goal loop into the net off his shoulder, Van Persie's second was an exquisite first-time finish, and the 29-year-old admitted it could be the pick of his seven Red Devils goals to date.
When asked if it was his best goal for the club so far, he said: "Maybe, I have to look at it again. But it felt good when it came off my foot."
Van Persie was quick to praise strike partner Wayne Rooney for the assist for the goal, adding: "Everything starts with a good pass, not many players can hit a pass like that.
"It was good build-up play before the goal, and when it came to him I knew that he could see that pass and actually give it exactly the way I wanted it.
"I think it's the first time we've both started together, I think we're both very pleased with that. But we're doing it together - Chicharito played really well today, we have Danny [Welbeck], we have a very good team with excellent strikers."
