Such is the nature of football, we rarely wait for a manger to part ways with a club before debating the men in the frame to replace him.
This time the man in question is Manchester City's Manuel Pellegrini, who has come under pressure following a nightmare week.
Away games at CSKA Moscow and West Ham, and a home tie with Newcastle United should have seen City secure six points and a comfortable passage to the next round of the League Cup, but that's not been the case.
A draw in Russia meant City's Champions League hopes are dwindling, while defeat in East London meant City fell six points behind Premier League leaders Chelsea, and now sit in third place behind Southampton.
Though the League Cup was never a priority for Pellegrini, being dumped out of it at home against an understrength Newcastle side simply rubbed salt into City's widening wounds.

- Manchester United will shock rivals City with surprise lineup
On Sunday Pellegrini takes on Louis van Gaal as City clash with United in the Manchester derby, and you can't help but think defeat could leave the man known as The Engineer unable to fix the situation.
While we don't expect the City hierarchy to make a quick decision, failure in the Premier League and Champions League would cast a doubt over Pellegrini's future, so we decided to cast our eye over five possible summer replacements.
