West Ham’s under-18 side crashed out of the FA Youth Cup at the first hurdle on Monday night, losing to Brighton on penalties.

But there were a few promising performances from the young Hammers, who are all hoping to be the next big thing in East London.

The rapid rise of Declan Rice and Grady Diangana has encouraged the new crop of youngsters at West Ham.

And Amadou Diallo is showing early signs that he could be the next big star at West Ham. But who is Diallo and how good can he be?

Who is Amadou Diallo?

Diallo has been a regular in West Ham’s under-18 team this season despite his young age.

The 15-year-old started in attack for West Ham against Brighton in the FA Youth Cup and scored an early goal.

Diallo also caused the Brighton defence a lot of problems and was unlucky not to pick up more than one goal.

Playing two levels above his own age group, Diallo scored his first goals last month, netting twice against Manchester City’s under-18 side.

The talented teenager followed that up with a strike against Reading and now his goal against Brighton takes his tally to four in three games for the under-18s, despite being just 15.

The England under-16 international is rated highly by club and country and there is genuine belief that he can go all the way to the top.

Any other promising youngsters?

West Ham’s under-18 side was captained by Ajibola Alese last night and he is an England under-18 international.

Goalkeeper Serine Sanneh is another England youth international, although he is usually just a back-up to Daniel Jinadu, who was injured.

Sean Adarkwa and Emmanuel Longelo were also in action for West Ham and they usually play in the under-23 side.
