Liverpool boss Jurgen Klopp admits Diogo Jota is carrying a back injury.
Jota struck the winner against Tottenham on Sunday, despite being unable to train last week.
Ahead of tonight's clash with Fulham, Klopp said: "If we have only three for three positions, it's easy to lineup, but we have five to name, it's just a job to do.
"Bobby (Firmino) is out, Diogo is struggling [back issue]. Couldn't train v Spurs but played and hasn't trained since.
"He is a doubt, I hope he recovers."
