Chelsea face a pivotal few weeks as they prepare for some big games in the Premier League, FA Cup and Champions League.
The Blues host Everton this weekend in the Premier League as they continue their quest to try and finish in the top four, with Frank Lampard's men currently sitting fourth in the table with a three point advantage over Manchester United in fifth.
But Chelsea have an injury crisis on their hands at the moment, with as many as ten players set to miss the game against Everton this weekend.
That includes the likes of N'Golo Kante, Mateo Kovacic and Ruben Loftus-Cheek.
Below, we look at the full list of players who could be missing on Sunday.
Tammy Abraham
The Chelsea striker has missed the last two games with an ankle injury.
He has said he is hopeful that he can return before the end of March, but he is not involved in training at the moment.
Andreas Christensen
The Danish centre-back is a doubt for Sunday with a knock.
He played the full game against Bournemouth last weekend, but missed the game against Liverpool in midweek with what Lampard described as a "small issue."
Callum Hudson-Odoi
The England international has suffered a recurrence of a hamstring problem this week, and is set for an extended spell on the sidelines.
Lampard said that Hudson-Odoi is now set for a scan to determine the extent of the injury, but he is likely to miss at least the next few games for the Blues.
Jorginho
The midfielder will miss the game against Everton through suspension, after picking up his tenth yellow card of the season against Bournemouth last weekend.
Jorginho will also miss the game against Aston Villa.
N'Golo Kante
The Frenchman has not featured since the 2-0 defeat against Manchester United last month, with Kante currently sidelined with a muscle injury.
He is currently ruled out, with no return date as yet.
Mateo Kovacic
The Croatian midfielder was added to Chelsea's growing injury list on Tuesday night, after limping off during the Blues' win against Liverpool.
It appeared to be an Achilles injury, and Frank Lampard has confirmed that Kovacic will not be fit for the weekend, but he is hopeful that he will be back soon.
Ruben Loftus-Cheek
The England international has not featured for Chelsea's first team yet this season, after a long lay off due to an Achilles problem.
He has, however, been stepping up his recovery in recent weeks as he closes in on a return to action, and featured in an in-house game at Chelsea's training ground at Cobham today.
However, Lampard admits that he is short of match fitness.
Christian Pulisic
The American international has not featured for Chelsea since the 1-1 draw with Brighton on New Year's Day.
But like Loftus-Cheek, he was involved in an in-house game at Chelsea's training ground, with the 21-year-old nearing a return to fitness.
Marco van Ginkel
The Dutchman has not featured for Chelsea during Lampard's time in charge, with the midfielder still yet to return from a serious knee injury.
Willian
The Brazilian is a doubt for the game against Everton, after picking up a knock against Liverpool.
At his pre-match press conference, Lampard said he was a question mark for Sunday and a late decision would be made over his fitness.
