Chelsea's title credentials will be tested this weekend when Aston Villa come to town.
The Blues, who were knocked out of the UEFA Champions League by Inter Milan earlier this month, saw their Premier League quest stutter last weekend as Blackburn claimed a 1-1 draw at Ewood Park.
Carlo Ancelotti's side returned to winning ways with a 5-0 thumping of Portsmouth on Wednesday and the Italian boss will be hoping his side have turned a corner after suffering a blip in recent times.
Villa meanwhile, squandered the chance to close in on the much coveted fourth-place as Wolves and Sunderland travelled to Villa Park and walked away with a share of the spoils.
Martin O'Neill's side remain unbeaten in the league in 2010, but seven draws in their last 10 games has seriously hurt the Villains' hopes of grabbing the last Champions League qualification spot.
Villa, though, boast a good top-flight record against Chelsea and have already beaten the Pensioners when they met earlier in the season.
But O'Neill's small squad are beginning to feel the effects of a gruelling season which has already seen them reach the Carling Cup final and with an FA Cup semi-final against Saturday's opponents looming, the Northern Irishman may decide not to risk some of his fatigued performers at Stamford Bridge this weekend.
Gabriel Agbonlahor has been absent since the win over Wigan with a groin problem and remains doubtful for the Chelsea encounter, while fellow striker Emile Heskey could also miss the London trip with an Achilles problem picked up in Wednesday's 1-1 stalemate against the Black Cats.
That leaves O'Neill with youngster Nathan Delfouneso as the only recognised forward to partner in-form John Carew up front so the Villa boss may return to the 4-5-1 formation which he deployed at the start of his tenure.
Steve Sidwell could be the benefactor of that team-selection to face his former club, although the former Chelsea man may start regardless as James Milner is Villa's second player to suffer with an Achilles problem.
The midfielder has been in scintillating form this season and looks a shoe-in to make England's World Cup squad fitness permitting, but the former Newcastle man was forced off the field midweek and could be given a well-earned rest
Richard Dunne, who looked out-of-sorts in midweek against Sunderland, is another player suffering with a sore Achilles but the defender managed to play 90 minutes last time out and should line-up in the division's joint meanest rearguard.
Chelsea, meanwhile, are enduring their own injury crisis with Ricardo Carvalho the latest player to face a spell on the sidelines.
The Portuguese defender damaged his ankle in the Fratton Park mauling midweek and will find out whether he will miss the rest of the season from Friday's scans.
Carvalho joins the likes of Ashley Cole (ankle), Branislav Ivanovic, Jose Bosingwa (both knee), Michael Ballack (Achilles), and Henrique Hilario (groin) on the treatment table
That means Ancelotti's only has two recognised centre-halves in the shape of John Terry and Alex, while Paulo Ferreira will continue at right-back and Petr Cech will retain his place in goal after making his comeback from injury last time out.
Michael Essien's return remains unknown after the midfielder admitted to set-backs on his rehabilitation on his injured knee.
Essien has been missing since January and it is unclear whether the Ghana international will be able to recover in time for Chelsea's run-in.
Possible starting XIs:
Chelsea: Cech, Zhirkov, Alex, Terry, Ferreira, Malouda, Lampard, Mikel, J Cole, Anelka, Drogba.
Villa: Friedel, Warnock, Collins, Dunne, Cuellar, Downing, Petrov, Milner, Sidwell, A Young, Carew.
