Aitor Karanka says he is proud of his players' efforts against Tottenham Hotspur as Boro fell to a 1-0 defeat at White Hart lane.
Boro stood firm in North London and held the home side to 0-0 at the break, but Spurs took the lead when Harry Kane converted a second half penalty.
"At the end we had a few chances to score," said Karanka. "We scored against Man City [in injury time] but today it was impossible.
"First half we went to the pitch knowing the other results put us under pressure and I told them at half-time that we had to play in the way we know how to play, without pressure.
"That's because when you are here [White Hart Lane] trying to something against Tottenham under pressure it's impossible.
"At the end of the game we had chances to score through Marten de Roon and Alvaro Negredo.
"Again, the players have done their best and I can only say good things because they put everything on the pitch in every single game."
Bernardo Espinosa brought down Heung-Min Son just before the hour mark which proved to be crucial in a game of few clear-cut chances and Karanka says he has no complaints with Mark Clattenburg's decision to award the spot-kick, but was encouraged by his team's showing.
"I think it was a penalty but we showed we can compete against the best teams," said the Boro Head Coach.
"Tottenham are second so it's just about keeping going because with these players, this attitude and this commitment we're going to win games, for sure."
