Liverpool have had a glimpse of what Alexander Isak can do. They have seen it on the training pitch. They have seen it in first-team football, too. Though, almost 11 weeks into his Anfield career, such evidence still all came at their expense, and not to their benefit.
There was the Isak who scored on his Newcastle debut at Anfield, the one who delivered what proved the decisive goal in the Carabao Cup final to deny Arne Slot a first trophy as Liverpool manager, the Isak who got four goals in six games against them. Which is rather better than his current return of one in eight for them.
