GRAHAM POTTER prepares for his first Premier League match in charge of Chelsea with key decisions to make.
The former Brighton boss, who replaced Thomas Tuchel in September, faced RB Salzburg in his first Blues game.
And he turned heads by playing Raheem Sterling at left back in the 4-3-2-1 formation.
Sterling scored, but Chelsea equalized and then faced a postponed game from Liverpool, as well as an international break.
It would have given Potter time to think about his next line-up, as he also played host to a secret friendly with the old Brighton side.
Kepa Arrizabalaga will keep his place in goal and Edouard Mendy will join N’Golo Kante on the disabled list.
If Potter wants to keep a three-man defense, Cesar Azpilicueta and Thiago Silva are likely to find themselves in the starting lineup.
That would leave summer signings Kalidou Koulibaly and Wesley Fofana, both on the bench against Salzburg, fighting for a place.
But alternatively, they would be the favorites to start if Potter selects a back four, with Silva and Azpilicueta unsuited for a central pairing.
Reece James has had a starring role in Chelsea’s start to the season and is expected to return at right back.

Marc Cucurella is suffering from an illness, which means Ben Chilwell is likely to play on the left.
Jorginho is the favorite to partner Mateo Kovacic in midfield, while Kante continues to struggle for form.
But Ruben Loftus-Cheek, Conor Gallagher and even Trevoh Chalobah, who played in midfield against Brighton, are also candidates to start.
In the future, Sterling is ready to go into the three opposing attacking winger.
And Mason Mount or Kai Havertz, both on target in England’s friendly against Germany, will compete to start on the opposite wing.
That is if Pierre-Emerick Aubameyang keeps his place at the helm, despite his slow start since joining from Barcelona.
But if the former Arsenal captain is dropped, Havertz or Armando Broja would be expected to replace Aubameyang.
