Chelsea manager Avram Grant pays tribute to Frank Lampard, who is on the verge of 100 goals for the club:
"Frank is a great player, a great professional.
"He has a lot of qualities and one of them is to score a lot of goals. He had a bad injury this season and didn't play for a month which is unusual.
"In the last few years he has played in all of the games but he is back with a lot of passion."
This game brings together the third bottom and third top clubs in the Premier League's "Last Six Current Form" table.
Blackburn' s midweek Carling Cup exit to Arsenal came on the back of a shock 5-3 defeat away to lowly Wigan when Roque Santa Cruz scored a hat-trick and ended up on the losing side. Rovers are now anxious to avoid three straight Premier League losses for the first time in over eight months.
Chelsea's home Carling Cup quarter-final victory over Liverpool, followed Sunday's league loss at Arsenal. The Blues go into their 600th Premier League game eager to avoid back-to-back defeats for the first time in 55 outings, since the end of the 2005-06 campaign.
The Londoners have gained one more league win away from home than Rovers have achieved at home in the current league campaign (five to four).
This is also a meeting of the two worst behaved clubs in the Premier League with a total of 79 cards being shown to Blackburn and Chelsea players in a combined total of 34 league fixtures so far this term.
Chelsea are chasing a sixth win in eight visits to Ewood Park, yet Blackburn have gained more Premier League points against Chelsea than any other club (41).
