London - Manchester United defender Patrice Evra insists his club's English Premier League title triumph proves that Robin van Persie was right to leave Arsenal.
Van Persie infuriated Arsenal fans by quitting their team to join rivals United in a £24m transfer last year.
The Dutch striker's goals played a key role in United regaining the English title, giving him a first major medal since the 2005 FA Cup he won with the north Londoners.
Inevitably, Van Persie was subjected to abuse from Arsenal supporters on his first return to the Emirates Stadium for Sunday's 1-1 draw with the Gunners.
Yet, despite the hostile reception, he showed respect for Arsenal by opting not to celebrate his penalty equaliser.
And French left-back Evra believes winning the title more than justifies the 29-year-old's decision to quit a club who have now gone eight years without a trophy.
"He hasn't made the wrong choice," Evra said. "It was a long time that he didn't win the league at Arsenal. He has come to Manchester United and won it.
"I still don't understand why the fans boo him. I am disappointed that the fans have quickly forgotten what he did for the club. I think he felt it as well."
