Isak made his Liverpool debut against Atletico Madrid on Wednesday in their Champions League opener as The Reds snatched a 3-2 victory in the dying minutes thanks to a Virgil van Dijk header.
The Swedish international clearly isn't at full fitness at the moment, and Slot admitted that he would not play a full 90 minutes if he did feature against the La Liga side. However, Isak did play for 58 minutes before being taken off and managed an impressive performance which included a shot on target.
Slot spoke after the game and revealed his surprise at Isak’s stamina considering his lack of game time so far, suggesting that he could be available for this weekend’s clash against Everton.
“I was positively surprised by how fit he was during that 60 minutes but that maybe, probably, tells you that it might be a difference to sign a 20-year-old from a different league or a 25- or 26-year-old that is used to playing in this league.”
“Although he only trained for two weeks, he has so many games under his belt that he is probably more able to be ready for 60.”
“Yeah, a good start, only 60 minutes and now we have to build him up from here. But I can tell you he is not going to play 90 again on Saturday.”
“I can tell David (Moyes), or you can tell David that he is not going to play 90 on Saturday.”
Isak has caused Everton plenty of problems in the past during his time at Newcastle and although Ekitike is likely to start the game, he may get his chance off the bench as he builds up to full fitness.
