Graham Potter claims he has the hardest job in football as injury-ravaged Chelsea struggle to live up to expectations following Todd Boehly's takeover of the Premier League club.

Pep Guardiola told Chelsea co-owner Todd Boehly to back under-fire boss Graham Potter after Manchester City thrashed the Blues 4-0 in the FA Cup third round on Sunday.

Chelsea boss Graham Potter said Sunday's 4-0 FA Cup loss to Manchester City was "painful" and he understood the supporters' reaction as the London side suffered a sixth loss in nine games to pile on more misery in the Englishman's short tenure.

Manchester City cruised to a 4-0 win at home to Chelsea in the third round of the FA Cup on Sunday, enjoying their third successive win over Graham Potter's side in the space of two months.

Graham Potter has revealed Chelsea's poor form prior to the World Cup almost ruined his holiday, but he now feels 'even more confident' than before.

Graham Potter's return to Brighton & Hove Albion turned into a nightmare when he suffered his first defeat since taking charge of Chelsea in a 4-1 loss in the Premier League on Saturday.
