New arrival Joao Felix has been handed a start for Chelsea versus Fulham in Thursday's Premier League game.
The Atletico Madrid loanee was only confirmed as a Chelsea player at midday on Wednesday and received his work permit earlier on Thursday.
However, the Portugal international has been drafted straight into the first XI, joining Mason Mount and Kai Havertz in the final third.
Graham Potter has opted for a back three of Trevoh Chalobah, Thiago Silva and Kalidou Koulibaly, with fellow new signing Benoit Badiashile remaining on the substitutes' bench.
Meanwhile, Cesar Azpilicueta and Lewis Hall have been given the nods at wing-back, leaving Marc Cucurella to remain among the replacements.
From the 4-0 defeat at Manchester City in the FA Cup, Bashir Humphreys, Conor Gallagher, Jorginho and Hakim Ziyech have all dropped out of the team.
Pierre-Emerick Aubameyang has returned to the squad after a minor back issue kept the forward out of the match at the Etihad Stadium on Sunday.
Fulham: Leno; Tete, Adarabioyo, Ream, Robinson; Palhinha, Reed, Pereira; De Cordova-Reid, Vinicius, Willian
Subs: Rodak, Diop, Kurzawa, Chalobah, Cairney, Wilson, Solomon, James, Harris
