It will be a London derby in the Carabao Cup semi-finals as Chelsea and Arsenal have been drawn against each other in the last four.
Meanwhile, Premier League leaders Manchester City will take on Championship upstarts Bristol City, who managed a stunning upset of Manchester United on Wednesday.
Chelsea led for most of their fifth-round match against fellow Premier League side Bournemouth, but a late goal from Dan Gosling appeared to be sending the match to extra time, only for an Alvaro Morata stoppage-time winner to ensure the Blues’s passage into the semi.
Arsenal found things a little more comfortable with a 1-0 win in another London derby, against West Ham United, on Tuesday.
Bristol City, currently sitting third in the Championship, are the surprise team in the draw.
Man City also saw drama in their quarter-final match, having it come down to penalties against Leicester City as they kept their quadruple hopes alive for the season.
