CHELSEA will be without Kalidou Koulibaly for their huge Champions League clash away at RB Salzburg on Tuesday evening.
The Blues currently sit one point above the Austrian outfit heading into their final two matches in Group E.
And Graham Potter will be keen to go into his side’s last match at home to Dinamo Zagreb having already qualified for the last 16.
But they will have to do so without summer signing Koulibaly as Potter confirmed the centre-back will remain sidelined through injury.
The Senegalese defender missed the draw with Manchester United because of a knee problem.
And Potter provided an update on Monday, saying: “Itâs not too serious but this game was too soon for him.
“Weâre hoping to get him back on the grass Wednesday or Thursday.”
With Wesley Fofana also out, it leaves Potter with a decision to make whether to will line up with a back three or four.
They started with a three against Manchester United but Potter substituted Marc Cucurella for Mateo Kovacic before half-time as Chelsea changed their shape.
And it means they could play a couple of different ways against Salzburg.

Either they line up with a three of Cucurella, Trevoh Chalobah and Thiago Silva, with Ben Chilwell and either Ruben Loftus-Cheek or Cesar Azpilicueta as the wingbacks.
That would then see Kovacic and Jorginho pair up in the midfield behind a likely front three of Raheem Sterling, Mason Mount and Pierre-Emerick Aubameyang.
But a more likely scenario is that Potter goes with a 4-2-3-1 shape, with Cucurella and Azpilicueta flanking Silva and Chalobah at the back.
They could then have Kovacic and Loftus-Cheek in front of the defence, with Sterling, Mount and Kai Havertz behind Aubameyang.
