Everton were much improved defensively at Goodison Park on Sunday.
The Toffees have looked porous throughout the campaign so far, with their tendency to concede cheap goals plaguing their season.
However, despite being on the back foot for much of their match against Spurs, Martinez’s men stood firm and the Spanish boss was delighted with his side’s new found solidarity.
"It's not the result it's the performance [that was encouraging]," Martinez said. "We have been a little bit lightweight in the way that we have defended our box and today was an incredible change.
"The way we defended was a really good platform for the performance. Spurs did have a lot of possession but we knew how to create clear-cut opportunities.”
Everton’s defence was only breached on one occasion against Spurs, with Dele Alli scoring the visitor’s equaliser in a 1-1 draw.
As good as the Toffees’ defensive performance was, they also had the Goodison Park woodwork to thank, as Tottenham did hit the crossbar twice in the early stages of the contest.
Everton remain in 11th place in the Premier League table after the draw, but their defensive performance has offered some reason for optimism.
The Toffees have had no problems going forward this campaign, and if they can continue to be so solid at the back then they should start climbing up the standings rapidly.
