Liverpool fans have seen Federico Chiesa play just 19 minutes of football since he joined the club from Juventus for £12.5m at the end of last month.
He could be set for his full debut today, though.
Asked about the Italian’s chances of a debut this evening, Slot said: “I don’t think he’s able to play 90 minutes. He only played 25 now, as a maximum, in the last three, four, five months
“But he’s able to start, in our opinion, and if he will, let’s see. There are many options that we have, but he’s able to start in our opinion.
But I don’t think he’s able to play 90 minutes at the level we are playing tomorrow against a strong West Ham team.”
