Nathan Ake's 88th-minute tap-in helped Manchester City end their Tottenham Hotspur Stadium hoodoo and progress into the FA Cup fifth round after a 1-0 away victory.
Pep Guardiola's side had failed to score in their previous five visits to Spurs' home and that unwanted record looked set to extend until Ake bundled home from close range after Guglielmo Vicario flapped at Kevin De Bruyne's corner.
All eyes had been on De Bruyne and Tottenham playmaker James Maddison after a lacklustre first half and while the former helped break the deadlock, it was an uncharacteristic City goal that fired them to a seventh straight win.
Ange Postecoglou's team could have little complaints and this cup loss means the club's trophy drought will almost certainly extend into a 17th year.
Chelsea were held to a lively goalless draw by Aston Villa at Stamford Bridge as both sides squandered opportunities to settle their fourth-round tie.
Mauricio Pochettino's team had scored six in their previous outing, dispatching Middlesbrough to reach next month's Carabao Cup final, but found Unai Emery's Premier League high-flyers a more obdurate hurdle as a combined 23 shots from both sides failed to yield a winner.
John McGinn spurned Villa's best chances in either half, while Emiliano Martinez twice denied Chelsea as Noni Madueke and Cole Palmer found themselves frustrated.
It was a theme of the night in west London as a replay at Villa Park beckoned.
Djeidi Gassama - pictured above - scored a late equaliser as Sheffield Wednesday claimed a 1-1 home draw against Coventry to earn a fourth-round replay.
Summer signing Gassama cut inside to level with a low shot in the 84th minute after Victor Torp had marked his Coventry debut with a stunning opener on the stroke of half-time.
Coventry were denied a second win at Hillsborough inside a week after their 2-1 Championship success on Saturday, which was marred by allegations of racist abuse towards their striker Kasey Palmer during the match.
Bristol City and Nottingham Forest fought out a goalless draw and will replay their fourth-round tie at the City Ground.
Forest will be glad to avoid the fate West Ham suffered in the third round at Ashton Gate when the Sky Bet Championship side produced a memorable upset against Premier League opposition.
But Nuno Espirito Santo's side will not welcome the extra game amid their battle to stay in the top flight.
Forest shaded the clearest openings during what was a pretty even affair but, in the end, had to settle for a rematch and the first clean sheet of Nuno's seven-game reign.
