Arsenal's under-19s take on Olympiacos in their second NextGen Series match of the season on Wednesday night.
Terry Burton's youngsters got off to the perfect start with a 3-0 victory over Marseille at Underhill almost two weeks ago.
But what is the NextGen Series?
Well, essentially it's an under-19 version of the Champions League. It is a European cup competition, played over the course of six months, for youth-team players from some of the biggest clubs in the continent.
It is based on a similar format to the Champions League and is designed to help the stars of the future prepare to play in that competition.
Arsenal are taking part for the first time this season after the success of the 2011/12 tournament, won by Inter Milan.
The Gunners have been drawn in Group Four alongside Marseille, Olympiacos and Atletico Madrid.
