Tottenham Hotspur surrendered a two-goal lead in their 2019/2020 Champions League opener against Olympiacos on Wednesday evening.
It's not the first time this season where such an instance has happened.
And Harry Kane - the scorer of the opening goal from the penalty spot - was not a happy man afterwards.
"Conceding before half-time killed our momentum," said Kane, as per the Evening Standard . "It happened against Arsenal as well. I’m not quite sure how they got through so easily.
"But especially away from home in the Champions League, you have to knit together, make sure you don't concede.
"Whether that’s being more compact, going direct and seeing out the clock or something else. At 2-0 up if we see it through to half-time it's probably a different game.
"At half-time, the gaffer said the players need to respect their positions more. We tried to do that. I don’t think we did it particularly well all game.
"Any time you’re 2-0 up away, especially in the Champions League, you expect to go on to win.
"It was a frustrating game."
But did Kane have another reason to be frustrated?
Some Spurs fans think so as Erik Lamela's decision to shoot rather than pass to Kane for a simple tap-in late on has been flagged up on social media.
