The forward, 17, was making his first start at this level for Keith Downing’s side.

Callum Hudson-Odoi opened the goalscoring for England in Tubize before the Belgians levelled things up.

Walker netted the winner to continue England’s impressive form, with qualification for the European Championships set to start in November.

Elsewhere, fresh from training with the senior side last week, Marcus Tavernier played as England’s Under-20s slipped to defeat against the Netherlands.

There was an ideal start for Paul Simpson’s side as Eddie Nketiah – the other youngster to link up with Gareth Southgate’s first team last week - put the Young Lions ahead with seven minutes played.

But the Dutch staged a second-half comeback, with Tahith Chong’s 62nd minute leveller followed up by Dylan Vente’s goal thirteen minutes later.

As England chased a way back into the game, Ferdy Kadioglu made it 3-1 in the closing stages.

Meanwhile, Nathan Wood has featured twice for England's Under-20s in the Syrenka Cup. 

The Boro defender started in a 6-0 victory over Norway on Friday, and featured from the bench in a 2-1 win against Portugal on Sunday. Belgium await in the final on Tuesday.
