After a hectic ending to the January transfer window for Chelsea, they welcome Fulham to Stamford Bridge in the Premier League on Friday night.
The Blues spent in excess of £300 million during the month, but need a mammoth turnaround to make the top four this season.
With the signing of Fernandez going through around the deadline on Tuesday night, he will be eligible to play here, but whether Potter will opt to throw him straight into the side is debatable.
Felix is still suspended after his red card in the reverse fixture, with this being the third and final game of that ban he has to serve.
After an exciting cameo against Liverpool, Mudryk could come into the side possibly to take the place of either Hakim Ziyech or Conor Gallagher, who both saw late transfers fall through on deadline day.
One player who did leave though was Jorginho, as the Italian midfielder joined London rivals and league leaders Arsenal, and with N’Golo Kante and Denis Zakaria both injured, Potter will hope to welcome back Mateo Kovacic for this one.
The Croatian midfielder missed the trip to Anfield with a calf problem, but the manager expects him to be fine to return to the side.
On the contrary, Fulham have virtually no injury worries coming into the game, with Neeskens Kebano the only current absentee.
Fulham were also busy on deadline day, as they were able to bring in Serbian international Sasa Lukic from Torino, who will link up with his compatriot Mitrovic in the squad.
Cedric Soares also came in on loan from Arsenal to offer more cover at right-back, with Kevin Mbabu seemingly not in Silva’s plans as back up.
Chelsea possible starting lineup:
Arrizabalaga; Chalobah, Thiago Silva, Badiashile; Azpilicueta, Kovacic, Hall, Cucurella; Mount, Mudryk, Havertz
Fulham possible starting lineup:
Leno; Tete, Diop, Ream, Robinson; Palhinha, Reed, Andreas Pereira; Decordova-Reid, Mitrovic, Willian
We say: Chelsea 2-1 Fulham
