Rovers were no match for Chelsea as they crashed to a 5-0 defeat at Stamford Bridge on Saturday evening.
They were blown away by a second half salvo of four goals in twenty minutes after Chelsea only had an own goal from Givet to show for their dominance in the first half.
But in the second half the goals flowed with Frank Lampard doubling the hosts lead just two minutes after the restart.
Michael Essien soon added a third with a 30 yard strike before Lampard scored from the spot after Nelsen had found Drogba.
Drogba himself then got in on the act with a headed goal as Chelsea made it 5-0 with still 25 minutes to go.
Thankfully there were no further goals added as Rovers ended the match with their best spell of the game, but it was far too little too late.
Before the game Sam Allardyce was forced into making four changes for the teatime clash.
Already without striker Franco Di Santo due to ineligibility, the manager's problems were further compounded by a calf injury to Pascal Chimbonda and flu victim's Chris Samba and David Dunn absence.
Jason Roberts replaced Di Santo up front, whilst Olsson slotted in at left back for Chimbonda, Givet replaced Samba and Emerton for Dunn. This meant a 4-1-4-1 formation with Steven Nzonzi given the task of protecting the back four.
Rovers could have been trailing at the Bridge without them even touching the ball when the home side almost netted from the kick-off.
Just thirty seconds were on the clock when a ball from the right by Frank Lampard picked out Joe Cole, but with the goal at his mercy he thankfully headed wide.
A chance then presented itself to Morten Gamst Pedersen on the edge of the area, but he delayed the opportunity to shoot and Ricardo Carvalho rescued the situation for the home side to rob the Norwegian.
The home side continued to press and probe with Frank Lampard and Joe Cole's midfield partnership impressing, but when Chelsea did eventually break the deadlock manager Sam Allardyce will still have been upset at the manner in which Chelsea took the lead.
Rovers were in an advanced position in the Chelsea half with men in the area, but from Morten Gamst Pedersen's cross failed to find anyone in a Rovers shirt, and from this Michael Ballack brought the ball through midfield to find Nicolas Anelka and his low cross was unfortunately bundled into his own net by a sliding Gaël Givet.
Drogba, Lampard and Anelka both went close for the home side as they looked to double their lead, whilst Pedersen fired wide for Rovers. Then Cech flapped at a Pedersen long throw but Essien cleared the danger.
Those were rare opportunities for Rovers however as they play was very much centred towards Paul Robinson's goal.
Anelka fired wide at the near post before Robinson, booed a the start of the match for his previous association with Tottenham pulled off a stupendous save in first half injury time. Frank Lampard sent the ball over from the right, Carvalho headed down and from close-range John Terry lashed the ball through the crowded area.
The ball seemed destined to be heading for the back of the net but Robinson was alert to dive full length to his right to somehow push the ball over the bar.
But any team talk given by Sam Allardyce at the break went right out of the window as Chelsea scored just two minutes after the restart.
Michael Essien threaded the ball through for Didier Drogba in the area, he swept the ball across goal, Lars Jacobsen did get a touch but only to divert it into the path of Frank Lampard and he made no mistake from ten yards.
Five minutes later and Rovers inability to close down the opposition proved costly once again. The Rovers midfield standing off long enough to invite Michael Essien to shoot and the man from Ghana didn't disappoint hitting a thirty yard effort that swerved away from Robinson and into the back of the net.
Jason Roberts made way for Nikola Kalinic and the young Croat went close after a scramble in the Chelsea box but his two shots were both blocked.
The clock hadn't reached the hour mark when the fourth goal was scored. Drogba had gotten the better of Ryan Nelsen on the edge of the area before he was brought down by the Rovers captain. Frank Lampard netting his second of the game with a strike straight down the middle.
Five minutes later and number five duly arrived when a Frank Lampard corner kick saw Drogba once again got the better of Nelsen to head home.
To their credit Rovers prevented Chelsea from adding to their tally further. The visitors enjoying their best spell of the match in the last twenty minutes.
But it was all too little too late.
Thankfully Rovers don't have long to dwell on this heavy defeat as they face Peterborough in the Carling Cup at Ewood Park on Tuesday. A chance to banish this game firmly from the memory.
