Romelu Lukaku scored the winner to secure Chelsea's place in the FA Cup quarter-finals with a battling 3-2 win at Luton Town, after Blues owner Roman Abramovich announced he was selling the club.
Abramovich confirmed he had put Chelsea up for sale, saying the decision is "in the best interest of the club" before kick-off and Thomas Tuchel's side started slowly on the pitch on Wednesday.
Saul Niguez cancelled out Reece Burke's second-minute opener against a much-changed Blues side, but Harry Cornick restored Championship side Luton's lead in the first half at Kenilworth Road.
Timo Werner equalised after the interval, before teeing up Lukaku with 12 minutes left to ensure Chelsea's place in the last eight, which will be played on March 19.
Burke glanced a header into the top-right corner from Luke Berry's corner after just 102 seconds – the fastest goal Chelsea have conceded in all competitions this season.
Tuchel's side levelled things up after 27 minutes when the ball fell kindly for Saul to curl into the bottom-right corner, before substitute goalkeeper Harry Isted expertly denied Saul, Kenedy and Romelu Lukaku within a frantic four-minute period.
Luton regained the lead after Malang Sarr's unconvincing offside trap allowed Cornick in to finish past Kepa Arrizabalaga following Carlos Mendes Gomes' throughball.
Chelsea boasted 82 per cent possession in the first 15 minutes after the interval, but their reward did not arrive until the 68th minute when Werner poked past Isted after a superb Ruben Loftus-Cheek long pass.
Werner turned provider for the winning goal, when he found space inside the area and drilled across for Lukaku to apply the finish with a sliding tap-in.
