While previewing the final time Arsenal visit White Hart Lane, Pochettino was shocked when Ossie Ardiles and Ricky Villa strolled into the room.
The two Tottenham Hall of Famers then quizzed fellow countryman Pochettino on his thoughts ahead of the landmark derby and the team's preparation before marking the meet with a picture.
"I haven't [seen] a derby for 20 years, I don't think," Villa began. "When I left the country, I didn't come back. It's a little bit important, no?"
"Yes, it's a bit important," Ardiles replied, with a smile.
Pochettino said: "Everything is OK, we are excited [and] waiting for the game. You know better than me what it means to play an enemy - a sporting enemy.
"As it will be the last derby at White Hart Lane, it will be special for our fans."
Villa responded: "The derby is special. Football is like life when you play the derby. I'm expecting good football, attacking football. A good game."
Tottenham and Arsenal meet at White Hart Lane on Sunday, with kick-off schedule for 4.30pm.
