"Fantastic game," Pochettino told BT Sport at full time. "We were sloppy and conceded two goals in nine minutes, but the character we showed was fantastic.
"I want to congratulate the players - 2-0 down in Turin to a team so difficult to break down. We deserved a victory more than a draw.
"We are more mature now. In the last few weeks, the team are growing and have stepped up. It's a good example of the capacity we have.
"The team was amazing in how they reacted. You need some luck always in football. The tie is open, Juventus are a massive team. We have the hope we can win in Wembley."
