Coventry piled the pressure on Stoke manager Mark Hughes with a shock 2-1 victory in their FA Cup third-round tie on Saturday.
Jack Grimmer's 68th-minute goal won it for the League Two side, after Charlie Adam's penalty had cancelled out Jordan Willis' opener at the Ricoh Arena.
Elsewhere, runaway Premier League leaders Manchester City marched on in their quest to win four trophies following a 4-1 rout of Burnley.
A defensive error enabled Ashley Barnes to give the visitors an unexpected lead, only for Pep Guardiola's men to take full control through two goals from Sergio Aguero and one each by Leroy Sane and Bernardo Silva.
