The 30-year-old was in electrifying form and scored a brace to help get coach Louis van Gaal’s team off to the perfect start.
“It’s a fantastic feeling to have scored those goals,” Robben told Fifa.com afterwards.
“I have to say, I’m just so proud of my team. It’s always nice to score a couple of goals but I’m far prouder of the side.
"I’m proud of our performance because that’s what really matters.”
After the perfect start to their World Cup campaign, Robben added: “We need to stay focused and just keep doing what we have been doing,” he said, “tomorrow we start again.”
