LIVERPOOL, England : Premier League leaders Liverpool will be without Trent Alexander-Arnold on Sunday when they travel to Southampton, manager Arne Slot said, adding that goalkeeper Alisson had returned to training but was not ready to play. "Trent isn't training with us, but he's getting there to be back with us soon," Slot told reporters on Friday. Alexander-Arnold withdrew from the England squad for the recent international break after suffering a hamstring injury against Aston Villa on Nov.
