Chelsea and Manchester City shocked in double giant-killing

Sky Bet League 1 Bradford served up one of the biggest shocks in FA Cup history as they hit back from two goals down to beat Chelsea 4-2 at Stamford Bridge.

And on an extraordinary day in the world's oldest knockout competition, Manchester City were also left reeling by a 2-0 defeat at home to Championship Middlesbrough.

Former Boro winger Andy Halliday was the Bantams hero as he fired home from outside the box to give Phil Parkinson's men a stunning lead with eight minutes left in west London.

And when substitute Mark Yeates fired home deep into seven minutes of injury time, one of the most miraculous results in the history of the competition was complete.

The visitors' starting line-up cost the princely sum of £7,500 - paid to non-league Guiseley for James Hanson in 2009 - while the total fee for Chelsea's parade of stars almost reached £200million.

Jose Mourinho's men had won all 10 of their home Premier League games so far this term - but Bradford were undaunted and signalled their intentions early when Andrew Davies forced a point-blank save out of Petr Cech in the 14th minute.

There was no hint of the excitement to come when Gary Cahill put Chelsea in front on 21 minutes and Ramires made it two with an excellent strike.

But Jon Stead reduced the deficit before half-time and former Chelsea junior Filipe Morais grabbed a surprise equaliser on 75 minutes before the late drama.

Meanwhile in the north-west Aitor Karanka's Boro were fashioning a result of similar magnitude as goals from Patrick Bamford and Kike sunk Manuel Pellegrini's stars.

Boro keeper Tomas Meijas kept his side in the game with a series of stunning saves in the first half before Bamford - ironically on loan from Chelsea - put the visitors in front of 53 minutes.

Albert Adomah beat keeper Willy Caballero to a poor Fernando backpass and prodded the ball goalwards for Bamford to slide in with the follow-up.

And Boro completed their own improbable win in injury time when Kike was slipped through by Bamford and shot past Caballero.
