Lisbon. Feyenoord. Paris. Now Real Madrid.
Manchester City have played nine games in Europe this season and thrown away leads in four of them, plus a quick collapse at Juventus. In the Premier League, you can add Manchester United, Brighton, Brentford and the rest.
Pep Guardiola admits he can't put his finger on why it keeps happening, and neither can the players.

Nathan Ake, usually a calm and composed head on and off the field, insisted after the Real Madrid defeat that City simply haven't learned from past experiences and that created a 'difficult' dressing room atmosphere at full time.
"To give it away like that is frustrating and hard to take," he said. "Especially because it's happened a few times now this season and we haven't learned from it yet so we have to do that as soon as possible."
Pressed on why the late collapses keep happening, the Dutchman admitted the squad still have no answer to that all-important question.
"It's difficult to be honest. We're trying to find the reason why," he added. "There are little details that some games you can get away with but these kind of games you won't get away with because they're a top team. The next one is coming thick and fast so we have to be ready.
"Against these kind of players you're going to concede chances. We know that, they have top players up front. Obviously we have to do better collectively as a team, as defenders. Most of the time we did well to keep them out. Eddy made a few saves, a few tackles here and there. That's what we have to do. But at the end we're winning 2-1 and we gave it away. That's the main thing."
Centre-back partner Ruben Dias was more damning.
He said: "Of course it's frustrating. It's always going to be a different kind of game between us and them and in the end there are chances both ways and you end up playing the last minutes with a 2-1 lead and you cannot let it go the way we did. We need to do better. It is as simple as that because in the end we can say all we want to say but you cannot allow it.
"Now it is a matter of belief. How much do we believe in ourselves and believe we can go through. Obviously, we're aware. We know exactly the game that we're going to play there. We've been there before. It will only be about how much we believe in ourselves.
"We just need to accept the moment we are in. What we did before is not enough. We need to do even better because we are in the moment that we are. We have to embrace it and become much, much better until we don't become much, much better and we won't be able to make it.
"But the good thing at the end of the day is that in this team, in this club, if we believe enough in ourselves and if we believe enough we're going to win it, we can do everything. We have enough 'gunpower' to pull off anything. But we need to believe in it. If we don't believe in it, then..."
