Tottenham Hotspur boss Mauricio Pochettino says his side was unlucky not to score against Besiktas on Thursday.
Spurs suffered their only defeat in the Europa League but a costly one as they drop to second in Group C with the Turks going on to win the group on 12 points.
"I'm disappointed because we dominated but in football, you need to score when you create chances and dominate," Pochettino said.
"We had clear chances but we were unlucky in front of goal. This is football.
"One minute in the second half changed the game and it's true, we dominated, but we needed to score. It's disappointing because we deserved more.
"We need to stop thinking about the Europa League for the time being, focus on the Premier League and the Capital One Cup and in February, think about this competition again."
Meanwhile, the Argentinean labelled the two floodlight failures as "laughable".
"We had a chat with the referee and you need to accept the situation," Pochettino is quoted as saying by the BBC.
"It's frustrating if that happens, it was laughable. It's not good for reputation of the competition."
