This weekend’s round of fixtures saw one of the most dramatic series of events in the recent history of the prestigious FA Cup.
It began in Cambridge on Friday night: Manchester United were held to a 0-0 draw by Cambridge United. The team sitting fourth in the Premier League were held by a team 13th in League Two.
It was an astonishing result as the likes of Angel Di Maria, Radamel Falcao and Robin van Persie could not find a way past a team made up of free transfers and a couple of academy products.
Friday evening’s stunning draw will mean Manchester United and Cambridge United will have to play a replay at Old Trafford a week on Tuesday to decide who will make it into the fifth round.
In any normal tournament, the result would have been the shock of the round, but not in the FA Cup. On Saturday, the series of seemingly ridiculous set of results continued as Championship side Middlesborough won 2-0 against the Premier League champions Manchester City.
Previously in the day, Swansea City were beaten 3-1 away at Blackburn Rovers, whilst Tottenham Hotspur’s loss to Leicester City - a club currently bottom of the Premier League - went under the radar.
Chelsea's players "must feel ashamed"
Most bizarrely of all was the mystery of how League 1 side Bradford City could come back at Stamford Bridge from 2-0 down to win 4-2 against Jose Mourinho’s Chelsea. The Portuguese manager spoke of his humiliation after the game.
“It's a disgrace for a big team to lose to a small team from a lower league," Mourinho told the BBC.
"Me and the players must feel ashamed.”
Amidst the drama, West Brom beat Birmingham City 2-1, Reading beat Cardiff City 2-1 and Alan Pardew’s Crystal Palace found a way to beat Southampton 3-2.
Meanwhile, Preston and Sheffield United, Sunderland and Fulham, and Liverpool and Bolton all drew their respective fixtures and will have to also play a replay next week.
In Sunday's fixtures, Aston Villa avoided a shock defeat against lower league opposition by beating Bournemouth 2-1. Bristol City could not overcome West Ham United and lost 1-0 at home.
In the late afternoon kick off, Arsenal won comfortably at Brighton. Despite conceding twice, the result was never in doubt as they were always in control of the tie, eventually winning 3-2.
