Manchester City manager Manuel Pellegrini has borne significant criticism in the aftermath of City's 3-2 victory over Bayern Munich in their Champions League Group D finale.
Pellegrini said he was sorry for the mistake to Graham Chase of the Telegraph, explaining that he forgot that his side needed to win by a certain margin to claim top spot.
"Before the match I knew we had to win 3-0 because we needed one goal more than they scored here.
"When they scored the first goal, I continued [thinking] that 3-1 was not enough because they had a better goal difference, so I continued [thinking] that we had to win by three goals, 3-0 or 4-1.
"After they scored the second goal, I didn't continue thinking about what happened if we scored four goals."
City took the 3-2 lead in the 63rd minute, but never found the needed fourth goal to steal Group D from homestanding Bayern in shocking fashion.
Former Manchester City midfielder Dietmar Hamann issued a harsh assessment of Pellegrini's management of that last half-hour.
Per an ESPNFC.com report: "Unaware that a 4-2 win would have sufficed, Pellegrini left top scorer Sergio Aguero on the bench, and Hamann said it was 'ridiculous' and 'scandalous' that the City boss and his coaching staff did not know the scoreline they needed."
With the knockout stage draw coming Monday, now is the time for City and their fans to let this trifling episode go.
Here are five reasons why Pellegrini's miscount is irrelevant in the big picture.
