Tottenham Hotspur head coach Mauricio Pochettino believes his team could have scored at least two goals away at Fiorentina on Thursday night.
After last week's 1-1 draw at White Hart Lane, Spurs needed to score at least one goal to make it through to the next round of the Europa League.
But they failed to take advantage of a number of goal-scoring opportunities allowing the hosts to score twice in the second half.
"We're all disappointed," Pochettino said after the game.
"We created a lot of chances in the first half and we maybe deserved to score two goals.
"We created good chances but this is football, we didn't score and in the second half, their first goal was our mistake and it was hard to come back after that.
"We played well and when you analyse both games, we deserved more and that's why we're disappointed.
"I thought we were better but they scored two more goals than us and that made it impossible to go through to the next round."
Pochettino's men will be looking to end a disappointing run of results started after the North London derby win over Arsenal when they take on Chelsea in the Capital One Cup final on Sunday.
