"If I'm being honest, quality wise I can still play in the Premier League. I know that, I've always been a confident person, so I have high expectations of myself," said Rooney.
"I came here expecting to do well, I think there was a surprise from people who had their opinions which is fair enough but I never doubted myself."
Rooney, join D.C. United last July and helped them to a huge midseason turnaround, scoring 12 goals and adding seven assists in 20 appearances as United went from last place to a playoff berth. He was named a finalist for the MLS Most Valuable Player Award.
It was a remarkable turnaround for a club that won three of the first four MLS Cups after the league launched in 1996 but had fallen on tough times in recent years.
