Five hours before Tottenham and Real Madrid clash at Wembley on Wednesday night, their respective under-19 teams will play in the UEFA Youth League.
It's a pivotal match in Group H of the competition for teenage talent with both Spurs and Real locked on four points, two behind leaders Borussia Dortmund.
Unlike its senior equivalent, only the group winners progress to the last-16 automatically, while the second-placed side have to get through a play-off round.
So before Cristiano Ronaldo and Harry Kane steal the limelight on Wednesday night, this match at Tottenham's training ground is well worth your attention.
