How Manuel Pellegrini may come to rue a lack of preparation. It seems quite incredible that a man known as 'The Engineer' could be so dodgy at maths, but the lack of planning could be incredibly costly to his side's Champions League ambitions.
After a stunning fightback from 2-0 down at the Allianz Arena on Tuesday night to lead 3-2, Manchester City had nearly half an hour following James Milner's third to try and find a winner.
But star striker Sergio Aguero remained, bafflingly, rooted to the bench. If Pellegrini wasn't going to use him even at this vital a time in the game, then what was the point in making their most important asset travel to Munich in the first place?
All became clear after full time, however, when Pellegrini showed an almost embarrassing level of naivety in admitting that he was unaware of the fact that a 4-2 victory would have been enough for his team to secure top spot. Something that literally everyone, apart from the man that needed to know, knew.
"I was tempted [to bring on Aguero] if we scored the fourth goal," he said after the match. "It was risky to continue with Silva. He can't play more than 75 minutes. It was important to be first in the group but not the most important.
"It was difficult to score two goals and I think that [David] Silva can't play more than 75 minutes."
It is simply incredible that he could not know (I mean someone somewhere must have told him), but it does, at least, put his decision-making into context. It is why Aguero warmed up but didn't come on, it is why Silva was removed prematurely and it is why he threw on Jack Rodwell for Edin Dzeko with stoppage time approaching.
Bayern were there for the taking, but the Chilean thought that the game was beyond his side.
In previous seasons it may not have mattered quite so much. Last season Manchester United eased through their group, finishing top, before running into Real Madrid in the next round. Galatasary, however, came second and were rewarded with a far easier tie against Schalke.
This season, things are a little bit different. Assuming that Chelsea and Barcelona secure top spot in their groups, and Arsenal avoid defeat in Napoli, Manchester City will be guaranteed a draw against Real Madrid, Paris Saint-Germain, Barcelona or Atletico Madrid in the next round.
Perhaps the only blessing is that they can't get Bayern Munich again, so soon. They may have beaten them away on Tuesday night in a superb display, but the German champions were sleepwalking through the game (much like the second leg of the last 16 against Arsenal in February). The Citizens were hopelessly dismantled when they went toe-to-toe in October at the Etihad.
Manchester City fans everywhere can only hope, then, that Pellegrini and his team don't pay the price for poor planning.
