Chelsea fought back twice from a goal down to earn a 2-2 draw against Brentford , taking the fourth round FA Cup tie to a replay at Stamford Bridge.
Brentford enjoyed the better of the first half and deservedly went ahead through Marcelo Trotta after he turned home the rebound after Harry Forrester's initial effort was saved, but a goal shortly after half-time from Oscar brought the visitors back on terms.
However, just when Chelsea were on top, Turnbull inexplicably brought down Tom Adeyemi in the area allowing Forrester to convert the spot-kick and put the Bees in front, but a curled effort from Fernando Torres rescued the Blues late on.
