The Dutchman's treble - including a goal of the season contender - took his league tally for the season to 24 but he was more interested in the overall prize than personal landmarks.
"It doesn't matter who scored, as long as we won the game. From the first minute, everyone played well and it was great to score so early and a great win for us," he told Sky Sports after the 3-0 victory.
"I am very happy but it is weird. I had to wait so long for my first title. It is a great feeling. It is a fantastic team and fantastic players.
"It is a championship for every single one of them. The staff, the managers, the physios. This is our 20th title, it is deserved.
Van Persie's second goal had the crowd off their feet - a breath-taking left-foot volley as he latched onto a long-range pass from Wayne Rooney.
"It was a great ball from Wayne," he added. "So the only thing I had to do was guide it right and hit it properly and it went in great but more important was the result.
"The second goal was one the best goals. I only had to time it right. Let me enjoy this moment, the next game is against Arsenal, but let me enjoy this moment."
