The Argentine lauded his side’s performance for the first 70 minutes at White Hart Lane yesterday.
The White Hart Lane side relinquished a two-goal lead against the Potters, with late strikes from Marko Arnautovic and Mame Biram Diouf robbing Spurs of their first three points of the campaign.
With the hosts two up at the break and cruising, the home faithful will be disappointed to see their side let Stoke back into the encounter and most will adjudge the result as two points dropped rather than one gained.
Despite the flat atmosphere at the final whistle, Pochettino has stated that Spurs have reason for optimism.
“In football it’s never closed until the final whistle,” the Argentine told BBC Sport.
“It’s disappointing. The team played very well for 70 minutes and the penalty changed the game a little bit.
"We need to be optimistic, look forward and keep working. From my position it was difficult to see what happened, I don’t know if it was a penalty or not, but until this moment we played really well and created chances.”
Harry Kane’s substitution robbed Tottenham of bite in the final third of the game, with the performance in the last 20 minutes by Pochettino’s men distinctly average.
With one point from their first two games and ambitions of qualifying for the Champions League this season, the North Londoners need to bounce back and quickly.
Spurs travel to face high-flying Leicester City next weekend in what will be another tricky game.
