Slightly frustrated to still be goalless at half-time, the lads marched home in the second half with another double from Tomas Pekhart and a glancing header from Leigh Mills (pictured right with Alex).
The win stretched their unbeaten run to nine games and they have still lost just once - now in 13 matches - this term.
"It could have been more convincing, especially in the first half when we had chances we didn't take," reflected coach Alex.
"It can get a bit edgy when you come in at half-time at 0-0 but the team have matured a little, didn't show any frustration or leave themselves open to counter-attacks and when the chances came again, took them. We went on to win it quite convincingly.
"The first two goals both came from crosses. Cian Hughton did really well for the first - he switched to wide right when we lost Jamie Davis to injury after only 10 minutes, he put a great cross in for Tomas Pekhart to finish from about seven yards.
"The second goal was almost a carbon-copy but this time came from the left with Kyle Fraser-Allen going direct, another fine cross and Tomas was there again.
"The third goal came via a free-kick and good delivery from David Hutton and Leigh Mills got in front of his marker and glanced home a header."
Spurs U18s: Button, Hughton, Martin, Archibald-Henville (Kasim, 75), Mills, Casey, Davis (Smith, 10), Livermore, Pekhart (Medley, 85), Hutton, Fraser-Allen. Unused sub: Stroud.
Alex Inglethorpe felt the style of our Under-18s 3-0 victory over Coventry City underlined a growing maturity within the squad.
