Goals from Charlie Lee, Andy Hodges and Andy Barcham put Jimmy Neighbour's boys in control and Kieran McKenna's fine second half striker wrapped up the scoring.
Coach Jimmy reflected: "We played very well in the first half. They had a young side but so did we - we started with six scholboys. That's ideal looking at next season.
"We scored after about five minutes, Charlie Lee got up and headed a corner in and just after that we had another corner, cleared to Kieran McKenna, he knocked it back in and Andy Hodges headed it home.
"For the third goal, Andy Barcham ran onto a ball just inside their half and a good strike in the box.
"The second half was the same. We passed the ball, kept it well, although they didn't put us under too much pressure.
"Kieran McKenna scored a goal half-way through that half, great strike with his left foot into the top corner.
"It was good to have the schoolboys out. We know who we are taking in next season and those lads are now involved with me. It's nice to see them play and get involved but they have to do it against stronger opposition as well."
Spurs U17s: Eyre, Welch, Wright (Daniels, 75), Hicks, Hodges, Jenkins, Watson, Lee (Dawkins, 75), Barcham, O'Hara (Stevens, 75), McKenna. Unused sub: Forecast.
