Mauricio Pochettino's charges could not get the better of a 10-man Burnley outfit at the weekend, drawing 2-2 with the relegation-threatened Clarets despite playing the entire second period with an extra player.
Still entrenched in mid-table obscurity, the Blues reside in 11th place in the rankings after Saturday's dismal showing, albeit just four points behind seventh-placed West Ham United with two matches in hand.
Here, Sports Mole rounds up Chelsea's latest injury and suspension news ahead of the contest with the Red Devils, who also took a point home from their clash with Brentford over the weekend.
Malo Gusto
Status: Major doubt
Type of injury: Hamstring
Possible return date: April 4 (vs. Man United)
Up-and-coming right-back Malo Gusto had to be replaced in the dying embers of the Burnley stalemate with a hamstring concern, although Pochettino did not deliver an immediate update after the game, leaving his availability for Thursday clouded in uncertainty.
Romeo Lavia
Status: Out
Type of injury: Thigh
Possible return date: Unknown
Summer midfield signing Romeo Lavia has been a perennial occupier of the treatment room all season long, and due to a setback in his recuperation from a thigh injury, the Belgian will not play again for the rest of the campaign.
Christopher Nkunku
Status: Out
Type of injury: Hamstring
Possible return date: Unknown
Another luckless 2023 arrival, Christopher Nkunku, has been sidelined since the beginning of March with his own hamstring issue, and while a comeback in April is not beyond the realm of possibility, no date has been pencilled in yet.
Wesley Fofana
Status: Out
Type of injury: Knee
Possible return date: Unknown
Nkunku's compatriot Wesley Fofana is still on the mend following his latest severe knee injury, and at the start of last month, Pochettino conceded that the defender is unlikely to play again before the campaign concludes.
Reece James
Status: Out
Type of injury: Hamstring
Possible return date: Unknown
Another injury-riddled defender, Reece James, is no closer to making his comeback from a hamstring injury, but Pochettino is keeping his fingers crossed that he will be available before the end of the campaign.
Lesley Ugochukwu
Status: Out
Type of injury: Hamstring
Possible return date: Unknown
Lesley Ugochukwu is yet to turn out for Chelsea in 2024 owing to a hamstring injury, and he is still undergoing his recuperation programme with no timescale on his return.
Carney Chukwuemeka
Status: Out
Type of issue: Knock
Possible return date: Unknown
Carney Chukwuemeka was initially said to have sustained a "slight knock" on international duty, but he ultimately had to withdraw from England's Under-21s squad and was unavailable for the draw with Burnley as well. Little is known about the midfielder's concern, but he is not expected to appear for the Blues on Thursday.
Levi Colwill
Status: Out
Type of injury: Toe
Possible return date: Unknown
Levi Colwill is working his way back from a painful toe injury and is still being restricted to his rehabilitation programme, so he will not be at Pochettino's disposal for the Man United visit.
Robert Sanchez
Status: Out
Type of injury: Unspecified
Possible return date: Unknown
Goalkeeper Robert Sanchez had only just come back from a knee injury and played two FA Cup ties before picking up another unexplained issue, which will render him unavailable this week as well.
Trevoh Chalobah
Status: Out
Type of injury: Unspecified
Possible return date: Unknown
Likewise, Trevoh Chalobah was added to Pochettino's injury list prior to the draw with Burnley, and information on his problem has been scarce too, but he will definitely miss the visit of the Red Devils.
Ben Chilwell
Status: Minor doubt
Type of injury: Knee
Possible return date: April 4 (vs. Man United)
Ben Chilwell could not contribute to the draw with Burnley due to a blow to the knee, but he had taken part in training prior to that stalemate and will be pushing to return for Thursday's contest.
CHELSEA'S SUSPENSION LIST
Chelsea have no suspended players for this match.
