Liverpool official news, Van Dijk and Bradley missed the Liverpool friendly match.
Slott told Liverpool's official website: "Almost everyone has maintained or returned to their health. Unfortunately, Van Dijk is absent today due to illness. We lack Alison, Joe Gomez is not there, and Bradley is also absent. But as of now, we have basically maintained an ideal health, and the new players have gradually adapted to the tactical requirements. We first look forward to today's training game, and then the next few weeks of the game."
When asked whether these four players may miss the Community Shield against Crystal Palace or the first round of the Premier League home game against Bournemouth, the coach replied: "Van Dijk will not be absent under normal circumstances. Joe Gomez and Bradley are in a more urgent situation, and Allison can return to the team in time."
