Jurgen Klopp expects more players to leave Liverpool following the summer departures of Danny Ward and Danny Ings.
Wales goalkeeper Ward joined Leicester in a £12.5m deal last month, while Ings left for Southampton in a Deadline Day loan deal, which is expected to be made permanent next summer.
With the transfer window still open in Italy, Spain, France and Germany, Klopp admits there could be further departures from Anfield.
"The window is only one way closed so we cannot buy any more but we can sell not in Premier League - but it is clear that a few things will happen," he said.
Summer signing Fabinho picked up a minor injury in Liverpool's 3-1 friendly win over Torino on Tuesday night and Klopp admitted he is not sure if the Brazilian midfielder will be available for the Renault Super Sunday clash with West Ham this weekend.
"His scan was clear but he was feeling ill [when he came in for training] and we sent him home again. I have not seen him [again] so far so we will see about his availability."
Klopp added: "We will see about the England boys and Dejan. They are all in different shape. Trent has had longer, which is good. Hendo is full of power but he hasn't been back long - it's Hendo though, you always think about him.
"But Dejan will not be available for the weekend. We don't have big issues but with these little things we need to think about if it is a risk or not and if it is a risk do we take that risk or not and all that stuff.
"At the end I'm pretty sure we will have a fantastic football team on the pitch."
