Liverpool have been dealt an injury concern during the international break.
New head coach Arne Slot has enjoyed a seamless start to life at Anfield since replacing Jurgen Klopp earlier this summer, winning all three of his opening Premier League games without conceding a goal.
The Reds made light work of arch rivals Manchester United before the break, running out 3-0 winners at Old Trafford to maintain their 100% record.
It has been a remarkable start to the season for Slot, albeit at an early stage of the campaign, particularly considering the relatively slow summer transfer window on Merseyside.
While Italy international Federico Chiesa ultimately arrived in a shock move from Juventus, Liverpool were snubbed by their leading midfield target in Martin Zubimendi.
Ryan Gravenberch is enjoying a fine run in the team in a deeper midfield role as Slot turns to internal solutions, though the Dutchman will have been concerned about another of his midfielders.
Alexis Mac Allister, who has played in every minute of the season so far, pulled up in training ahead of Argentina’s World Cup qualifier with Chile on Friday.
Manager Lionel Scaloni told TyC Sports: “Alexis didn’t train because he was overloaded, he was in pain. It always happens to us, they come out to do their part.
“We’ll wait and see how he responds today. It doesn’t change our way of playing much because we’ll stay the same, but it’s true that he gives us play, set pieces. The rest of the team is more or less decided.”
Argentina meet Chile on Friday before traveling to Colombia on Tuesday, while Liverpool are back in action when they host Nottingham Forest on Saturday 14 September.
