Tottenham boss Antonio Conte was left frustrated after their 3-1 defeat to Arsenal on Saturday.
Spurs saw Emerson Royal sent off as Arsenal were worthy winners on the day.
Conte said, "I think the first half was in the balance. We had many chances to score. We made a big mistake with the last pass because we had great space. In the second half we conceded a second goal early and we could do much better.
"With the the red card, [went] the game. It was a really difficult game after that. We had to change totally then. It was the referee's decision and I don't want to comment.
"We had the opportunity to exploit much better and stay up and I repeat that I think we made big mistakes in the last pass and with easy passes but it happens and straight after the national team it is a bit difficult because players arrive at a different time.
"Now we have to move on but we know our role in this league and we have to try and do our best to stay close to the other teams at the top. I tried to give minutes to players because the game had ended and also to try and save energy.
"I wanted to give players time especially [Oliver] Skipp and [Matt] Doherty because we need the whole squad because we have many games in front of us in a short period."
