FA Cup review:Leyton Orient succeeded where Barcelona could not this week when Jonathan Tehoue's late equaliser secured an FA Cup draw against Arsene Wenger's side and a lucrative trip to the Emirates Stadium in 10 days time.
Arsenal looked comfortable throughout and the result seemed in no doubt after Tomas Rosicky headed the Gunners into the lead in the 53rd minute, but Tehoue’s 89th minute strike drastically changed the script.
The Frenchman took his goal brilliantly when a neat shuffle allowed him to skip between two Arsenal defenders on the edge of the box and before drilling his low shot past Manuel Almunia.
Orient will head to the Emirates with the added incentive of another dream tie against Manchester United in Old Trafford in the quarter-finals, after the draw was made earlier this afternoon.
Manchester City's expensively-assembled squad of stars were indebted to 34-year-old free transfer signing Patrick Vieira for getting them past League One Notts County in their FA Cup fourth-round replay.
With City's €58 million strikeforce of Mario Balotelli and Edin Dzeko struggling to trouble a team 59 places below them it was left to the veteran Vieira to score with headers either side of half-time.
That gave Roberto Mancini's side the breathing space they needed, having weathered an early storm, and substitute Carlos Tevez, Dzeko and Micah Richards all scored in the final six minutes to distort the scoreline as City ran out flattering 5-0 winners.
City now face a delayed fifth-round tie at home to Aston Villa, with the winners of that facing Everton or Reading in the last eight.
Ivan Klasnic's second FA Cup goal in four days secured Bolton a 1-0 victory over Fulham and a quarter-final trip to Birmingham.
The Croatian striker scored the winner in Wednesday's fourth-round replay against Wigan and he was on hand again here to volley home from 12 yards.
Fulham welcomed Bobby Zamora back into action after five months out with a broken leg but they could not find a breakthrough in a fractious encounter at Craven Cottage.
FA Cup quarter-final draw
Stoke v West Ham or Burnley
