Manchester City boss Pep Guardiola has never experienced a season like this in his managerial career.
A record run of defeats, an injury crisis, uncertainty over his contract and a rapid squad rebuild approaching.
Guardiola said his sleep and diet were being affected by an "ugly" state of mind around his side's crisis, and he came to one post-match news conference with very visible "nervous" scratches all over his head.
In December BBC Sport columnist Guillem Balague - who has authoured biographies on Guardiola - wrote about the City manager's "insecurities" and "huge self-doubt".
