Sunderland's U21 team beat Tottenham Hotspur's development side 1-0 on Monday night.
Sunderland beat Tottenham's under-21 side 1-0, putting in an excellent performance, and Stockdale was particularly pleased with two members of his team.
“The most pleasing aspect of the game today was our play off the ball,” said Stockdale. “Defensively we were very organised, tactically we were very aware and to a man we dealt with the way they tested us throughout the game.
“At times we could have kept the ball a little bit better but we were a constant threat on the break, we also had a relatively new back four including young Josh Robson who did ever so well and Andrew Cartwright who switched to centre back, so all these things add up to a really good away performance.”
Tottenham's youth system is one of the most highly-regarded in the country, so for Sunderland to have been able to beat them should be encouraging.
The Black Cats have an ageing first-team squad and they are likely to be relying on members of their youth team to make the step-up soon, as the club look to move forward.
It has been a long time since Sunderland had an academy graduate break into their senior squad, but their current crop look to be a promising generation.
As well as Robson and Cartwright, the likes of Duncan Watmore, who scored Sunderland's goal against Tottenham, and Mikael Mandron are tipped to have bright futures and they will all be hoping to get senior opportunities in the coming years.
