Two nightmare halves in as many games have seen clouds gather over the Etihad Stadium, while also marking an unwanted first for the manager
This week has given Pep Guardiola and Manchester City precious little to cheer, and it will go down as one of the worst in the coach's illustrious career.
City appeared to be cruising to the Premier League title midway through Saturday's derby against Manchester United, as goals from Vincent Kompany and Ilkay Gundogan established a 2-0 lead.
United, however, came firing back after the break and Paul Pogba's double formed the foundation of a famous three-goal comeback for the visitors.
Guardiola and City needed victory to seal the crown, but they will now have to wait at least another week to close out what still seems an inevitable victory.
More alarming, though, is a suddenly leaky defence that is worse than anything Guardiola has experienced.
