Jonathan Tehoue scored a fairytale equaliser in the dying minutes as Leyton Orient stole a 1-1 draw with Arsenal in the FA Cup fifth round.
Tehoue, substituted on at the hour for fellow striker Scott McGleish, danced between Kieran Gibbs and Ignasi Miquel in the 88th minute and fired a sublime low strike under Gunners goalkeeper Manuel Almunia, prompting wild celebrations in the stands at Brisbane Road.
It was a stunning end to the League One side’s tie with the mighty Arsenal, who controlled the match from the outset and took a deserved lead in the 53rd minute through Thomas Rosicky.
The Czech Republic midfielder rose to meet Nicklas Bendtner’s cross and unleashed a powerful header beyond Orient custodian Jamie Jones for his first league goal in more than a year.
Arsenal boss Arsene Wenger made wholesale changes following the Gunners’ midweek defeat of Barcelona, with only Alex Song retaining his place in the side.
The manager handed 18-year-old Spanish centre-back Miquel his debut in the Arsenal shirt, as well as starts to Bendtner, Bacary Sagna, Andrey Arshavin, and Maroune Chamakh.
But the final result will no doubt displease Wenger, with a fifth-round replay at the Emirates now added to Arsenal’s already busy schedule.
Meanwhile, two goals from Patrick Viera helped Manchester City beat Notts County 5-0 in a fourth-round replay.
League One side Notts County impressed during the early exchanges with a Karl Hawley shot hitting the post before Yaya Toure was forced to block Neil Bishop’s effort.
Krystian Pearce headed over from a corner and City goalkeeper Joe Hart could only parry Alan Gow’s free-kick.
Roberto Mancini’s hosts eventually worked their way into the game, with full-backs Aleksander Kolarov and Micah Richards both going close.
But City’s expensively assembled strike force of Mario Balotelli and Edin Dzeko struggled to find their rhythm and it was left to veteran midfielder Viera – a four-time FA Cup winner with Arsenal – to break the deadlock, heading the home side in front on 37 minutes.
County pressed for an equaliser early in the second half, but heads dropped when Viera struck again, connecting with a Kolarov corner to make it 2-0 on 58 minutes.
Balotelli was replaced by Carlos Tevez on the hour mark and the Italian made no secret of his displeasure at being withdrawn, storming straight down the tunnel.
Tevez eventually made the score-line comfortable for City when he rounded opposing goalkeeper Stuart Nelson to score in the 84th minute, before Dzeko and Richards struck late on to flatter City.
They will now play the winner of match between Everton and Reading for a place in the semi-finals.
Elsewhere, an Ivan Klasnic strike in the 19th minute at Craven Cottage gave Bolton Wanderers a 1-0 win over Fulham in an all-Premier League fifth-round tie.
Croatian front-man Klasnic was on target in Bolton’s fourth-round replay win over Wigan last week and he repeated the feat in West London, netting the winner with a volley from 12 yards out.
Bobby Zamora came off the bench in the defeat to make his first appearance for Fulham since suffering a broken leg in September.
Bolton will now face Carling Cup finalists Birmingham in the last eight.
