If Justin Kluivert makes his debut for the Netherlands in Friday's friendly against England at Amsterdam's Johan Cruyff ArenA, he will be taking the next step on a journey that began in earnest just across the road on a tiny five-a-side pitch in the autumn of 2008.
The "boardingpitch," as it is informally known at Ajax, is a small, artificial grass pitch flanked by rebound boards that stands tight against the northeastern corner of Stadion De Toekomst, home of the Ajax reserve team, at the heart of the Amsterdam club's De Toekomst training centre.
