Ajax's Naci Unuvar, 15, became the UEFA Youth League's youngest ever goal scorer as he converted a late penalty during a 6-0 victory over AEK Athens.
The Amsterdam giants' under-19s, managed by John Heitinga, kicked off their campaign in style as they took an early lead through Nicolas Kuhn, before Che Nunnely and Victor Jensen put the hosts 3-0 ahead before half-time.
Sontje Jansen then made it four after the break and it was soon five when Sergino Dest took advantage of a goalkeeping error, but it was sixth of the day which made history.
Unuvar stepped up to take a late penalty and, despite the goalkeeper getting a hand to it, the ball found its way into the back of the net.
The record had previously held by another Ajax youngster in Ryan Gravenberch.
