Chelsea are back in Premier League action this weekend as they host West Ham United in a London derby at Stamford Bridge.
The Blues welcome Manuel Pellegrini's men to SW6 on Saturday, with Chelsea looking for a return to winning ways after their first Premier League defeat in seven games as they lost 2-1 at Manchester City last weekend.
Chelsea were also in action in the Champions League in midweek, with Frank Lampard's men drawing 2-2 in Spain against Valencia to leave them needing a win against Lille in their last group stage game to qualify for the knockout stages.
Lampard will have a few decisions to make when it comes to his team selection for the game against the Hammers, but who will start on Saturday.
We take a look at the options for the Blues, below.
Chelsea correspondent Oliver Harbord
West Ham are in an awful way right now and Chelsea really have to take advantage of that and get all three points.
For Frank Lampard it will be a big game, managing against his former side, but there won’t be any love lost there between them.
Mason Mount has been on the bench for the past couple of games, but I would bring him back in to play in the number ten role in a 4-2-3-1.
That would mean that somebody drops out, and it could be a harsh way to go but I might give Jorginho a break for the game, playing N’Golo Kante and Mateo Kovacic in midfield.
Even though the hip injury doesn’t seem too serious for Tammy Abraham, it’s expected that Saturday might be too soon for him, so Michy Batshuayi could get his chance.
I’d stick with Reece James at right-back as well, with the youngster having impressed when he has played so far.
Oliver's team (4-2-3-1): Kepa; James, Zouma, Tomori, Azpilicueta; Kovacic, Kante; Willian, Mount, Pulisic; Batshuayi.

Andreas Christensen’s inclusion against Valencia took everyone by surprise but he failed to impress and Fikayo Tomori should come back in on Saturday.
Reece James was outstanding before running out of gas late on and needs to continue at right back with Cesar Azpilicueta on the left.
Michy Batshuayi will start up front unless Tammy Abraham makes an unlikely recovery from his hip injury.
And Mason Mount might be brought back into midfield from the start because rotation will be crucial during a busy spell.
Still, it is hard to say who Frank Lampard gives a breather to. Mateo Kovacic, who was very good at the Mestalla, seems marginally more likely than Jorginho and N’Golo Kante.
Alan's team (4-3-3): Kepa; James, Zouma, Tomori, Azpilicueta; Kante, Jorginho, Mount; Willian, Batshuayi, Pulisic.

Frank Lampard doesn't need to make drastic changes to his side, after a first defeat in the league since September.
He did bring in Andreas Christensen for the Champions League clash in midweek, but after an indifferent display, it is likely that Fikayo Tomori will return against West Ham to partner Kurt Zouma at the heart of the defence.
Mason Mount has been on the bench for both games this week, and could find himself there again, with Mateo Kovacic impressing again against Valencia, while Willian and Christian Pulisic have done nothing to deserve being dropped.
The other change he could make would be up front, with Tammy Abraham coming off after taking a bang to the hip on Wednesday night.
Lampard said he hoped it was not too serious, but he could give a chance to Michy Batshuayi, if Abraham is not fit to face the Hammers.
Robert's team (4-3-3): Kepa, James, Tomori, Zouma, Azpilicueta; Kante, Jorginho, Kovacic; Willian, Pulisic, Batshuayi.
