Tottenham fullback Ben Davies was left frustrated after their Champions League defeat to Inter Milan.
Inter stunned Spurs with two goals in the final ten minutes.
Davies, "We did not have to concede what we gave away in the last few minutes, we had to be more careful in many situations.
"The defence lost confidence? No, it's not like that, I do not agree. We have to go back to the training ground to work and try to improve.
"We did not want to lose this game, the coach was very angry.
"Too many goals from set pieces? It is frustrating, as we must go back to work right away to correct our mistakes."
