Arjen Robben has been terrorising defences since he landed in Brazil last month – and the winger admits he is just having fun.
Robben was instrumental in Holland's World Cup opener, netting twice as Louis van Gaal's side crushed reigning champions Spain 5-1.
He followed that up with a goal against Australia and won the all-important penalty that saw Holland complete a dramatic turnaround in their last-16 clash with Mexico.
The 30-year-old came under some pressure following that clash, accused of diving to win the spot-kick before admitting to simulation earlier in the game.
However, he is eager to move on from that debate and continue to power Holland towards a second straight World Cup final.
"I'm having a lot of fun and really enjoying it here," said Robben. "In the second half [against Mexico], I was on the ball more and I could threaten the opposition going forward. That's a nice feeling.
"I just feel very strong. I feel good, I feel fit, and I think that's the most important [thing] because I can transfer everything on to the pitch.
"I can play my football and I'm really happy that I can help the team. I think we (the senior players) also have the responsibility for the younger guys.
"We try to take them along and I think we've got a good mixture of experience and youth at the moment. Again, everything we do, we do together and it was beautiful to turn the [Mexico] game around as a team."
Costa Rica – one of the tournament's surprise packages – lie in wait in the quarter-finals and Robben is well aware of the threat they can pose.
Fulham playmaker Bryan Ruiz and Arsenal striker Joel Campbell have both shone for Jorge Luis Pinto's side, who have knocked out England, Italy and Greece already.
However, Robben believes Holland – the tournament's highest-scoring outfit in Brazil – can put an end to Costa Rica's fairytale.
"I think they're a very strong team. We have to stay focused," he added.
"Costa Rica have a very good team, they have already proved that in their group, which was very tough, with Italy, England and Uruguay in there.
"They've been really impressive and we'll have to prepare very well if we're going to beat them."
