Mauricio Pochettino says Tottenham were the better side despite losing 2-1 to Premier League champions Chelsea.
The Lilywhites were beaten by goals from Marcos Alonso at Wembley as Michy Batshuayi scored an own-goal after coming off the bench.
"I'm very disappointed but at the same time, happy, because the performance was good," Pochettino told Sky Sports.
"Our fans were fantastic as always and I'm disappointed for them, disappointed for our team.
"I think we deserved more and played much better than Chelsea and that's why we're disappointed but happy, because if we play that way, we will win a lot more games.
"Chelsea were clinical, they scored in the key moments and for us, the chances we created we found impossible to score. That is the key of the game."
