Slot explained that Isak has had the opportunity to participate in the usual pre-season training and has been working to regain his fitness. He stated, "Now he has had his five, six weeks of pre-season which is normal for every player, especially if you have been out for three or four months."

Slot also mentioned that Isak's pre-season has allowed him to build up his endurance, playing 70 to 90 minutes in recent games. He expressed optimism about Isak's ability to make a positive impact on the team, saying, "Fitness-wise he is close to the level he should be and we can judge him in a fair way from now on."

The upcoming match between Liverpool and Manchester United on Sunday is expected to be a significant contest in the Premier League. With Isak back to full fitness, he could potentially be the difference maker for Liverpool as they aim to climb to the top of the league table.

The history between Liverpool and Manchester United is rich, with the two teams having met 243 times in competitive games. Their head-to-head record in the Premier League stands at 29 wins for United and 20 for Liverpool, with 66 encounters overall.
