Leicester could have drawn level on the hour mark, but Jamie Vardy, on off the bench, saw his spot-kick saved by Lloris.
"In some days it's hard to deal with Wembley, but hopefully for this big game we'll receive this help from the crowd". I am so happy.
"I have to congratulate the players".
"Again, their effort was fantastic".
He said: "More than anything I decided on Tottenham because there was an Argentinian manager and support team - or they can [at least] speak Spanish - and because it was a club that supported young players a lot".

"It was the same referee, but now I don't know how he has measured the situation", Pochettino said, as quoted by the Mirror.
Jurgen Klopp's men maintain the advantage of a game in hand, but handed a reprieve by Liverpool's draws against Leicester and West Ham in recent weeks, City look determined to become the first side in a decade to retain the Premier League. We have had a lot of opportunities, not just the penalty.
"Of course his quality is there and we can not doubt that".
The Lilywhites sealed all three points thanks to goals from Davinson Sanchez, Christian Eriksen and Son Heung-min, but it was the decision of referee Oliver that caused the biggest talking point of the afternoon - with Son booked for simulation despite being seemingly felled by the outstretched leg of Foxes defender Harry Maguire.
Son appeared to be tripped by Leicester defender Harry Maguire in the first half but Oliver brandished a yellow card to the South Korea global with replays showing Maguire's boot had made contact with his shin. "Unbelievable, unbelievable, unbelievable", Pochettino told reporters after the game. "Unbelievable, unbelievable, unbelievable", Pochettino said.
Leicester were awarded a penalty in the second half, which Jamie Vardy missed, when midfielder James Maddison appeared to be fouled by Spurs defender Jan Verthongen.
