Liverpool secured a dramatic win over Burnley thanks to a 94th-minute Mohamed Salah penalty, but the spotlight quickly shifted to injury concerns.
Fans were surprised to see Alexander Isak missing from the squad list, while Alexis Mac Allister was forced off after a heavy tackle.
Curtis Jones also sat out the match after picking up an issue before the international break.
With the Champions League opener coming on Wednesday, Arne Slot is anxiously waiting for updates on three key players.
Alexis Mac Allister
Alexis Mac Allister took a knock in the second half against Burnley and was substituted after receiving treatment. He has struggled with fitness throughout the summer and missed parts of pre-season.
After the match, Arne Slot confirmed the issue was minor, explaining the change was more tactical. According to Slot, Mac Allister said he was fine to continue, even though he was visibly limping.
Expected return date: September 17 vs Atletico Madrid (H)
Alexander Isak
Alexander Isak was a surprise omission from the squad to face Burnley. The striker is still regaining fitness after missing most of pre-season and playing only briefly for his national team.
Slot admitted that the club preferred to give him more time to prepare for the upcoming Champions League match rather than risk him too soon.
Expected return date: September 17 vs Atletico Madrid (H)
Curtis Jones
Curtis Jones missed the Burnley clash after suffering a knock against Arsenal before the international break.
Slot confirmed he would not be available but added that the problem is not considered serious. No return date has been given yet.
