"I went to Barcelona as an 18-year-old, as part of a youth training camp when I was at Yokohama Marinos," said Nakamura. "We were just training in the city and playing against different local teams. We went to a Barca game but I haven't been lucky enough to be on the pitch yet.
"When I was there, Rivaldo was the big star and he was the most impressive player I saw. It was my first football game outside of Japan and it was incredible. Barcelona are a team I grew up admiring, so to be on the pitch is a great honour.
"They are one of the top five teams in the world. Today, very few teams play like them. You look at Manchester United or Chelsea, who are also top teams. They have great individual players like Cristiano Ronaldo but there is still a cautious style at times.
"With Barcelona, it's different. They have so many top attacking players and play in a unique way. They are always free-flowing. Barcelona will be hard to beat. They are very good at keeping the ball, so we have to be patient. The most important thing is for us to make good use of the ball.
"We must also use the experience of the last-16 game with Milan last year. We have to use that disappointment to drive us on. Being on that San Siro pitch and feeling the hurt of being put out was hard but we can learn from that."
