The Dutchman was thrilled to get his hands on a Premier League winner's medal after failing to manage it during eight seasons with the Gunners.
He said after lifting the trophy: "It was amazing, it was heavy!
"I couldn't have wished for this year to be any better, only in my wildest dreams could I have wished it be like this."
He also hailed Sir Alex Ferguson, adding: "For me it was a massive honour to have worked with him. I want to thank him, he's been unbelievable. He's a great manager and an even greater person. He deserves all the credit. He's amazing."
On finding out Ferguson was leaving, Van Persie added: "It was a really sad day. Everybody understands it."
