Armando Broja came off the bench and scored the winner with his first Premier League 2 goal as Chelsea beat Blackburn Rovers 2-1 to reclaim top spot in Division 1.
Jonathan Russell gave the Blues a half-time lead and, although Daniel Butterworth levelled in the 74th minute, Broja struck decisively just two minutes later.
Chelsea move above Derby County on goal difference with a match in hand, after the Rams were held to a 2-2 draw by Wolverhampton Wanderers on Friday. Blackburn drop to eighth.
