Andre Villas-Boas was proud of Tottenham's performance in defeat at Arsenal as Emmanuel Adebayor's red card proved costly.
Spurs were leading through an Adebayor goal when the striker was sent off for a lunge at Santi Cazorla, leaving his team-mates to play more than 70 minutes a man short.
Arsenal raced into a 4-1 lead and, although Gareth Bale's strike briefly threatened to spark a fightback, Theo Walcott scored in injury-time to make it a repeat of February's 5-2 scoreline.
Villas-Boas said: "I think the sending-off determined the game, but the referee made the right decision. Players want to dispute the ball, there was no intention to do any harm.
"I'm very, very proud of the team. We had chances for 4-3 and if it had gone to only a one-goal difference, I think we could have gone all the way.
"We had the ambition and desire and I am extremely proud of the team."
