Both Dutch players excelled in Saturday's friendly between Netherlands and Northern Ireland and it is no coincidence that the two find each other so easily on the pitch
The Barcelona winger, who found Van Persie for the first goal, spoke of his very good understanding with the Arsenal striker, both on and off the pitch.
"That has been true since we first played together. I felt the 'click'. That’s what we call ‘football language," Afellay told ANP.
Against Northern Ireland the winger scored two goals and also provided two assists, having played fantastically on the left side of midfield.
"From the left I can cut inside and outside again. The opponent doesn't know what I’ll do next," the former PSV man stated.
"The important thing is to have confidence in yourself and trust the people with whom you work daily."
Although Afellay missed most of the 2011-2012 season at the Blaugrana because of injury, he hopes to get a starting spot against Denmark this Saturday.
"It happens in football, I don't look at it [the injury] anymore. It's good that I can be on the pitch again. I enjoy every moment of it," concluded the 26-year-old.
Netherlands will begin their Euro 2012 campaign against Denmark on June 9.
