Our Under-18s suffered their first defeat of the year after going down to Manchester City at the Etihad Campus.
Three goals in 14 first half minutes effectively settled the game in favour of the home side.
Alex Robertson netted in between two Carlos Borges goals to give City a 3-0 half-time lead.
Returning from injury, Josh Coburn was introduced as a second half sub for Boro and he pulled a goal back from the penalty spot with 15 minutes remaining.
But City swiftly restored their three-goal cushion when Norwegian U17 international Oscar Bobb made it 4-1.
Mark Tinkler's side remain fifth in the table, above Everton on goal difference.
