Alexander Isak is being linked with a transfer out of Liverpool less than a year after joining from Newcastle United for a record £125million.

What happened?

Isak's first season at Liverpool was marred by injury, including a fractured ankle in December, which limited him to just 21% of his team's minutes.

He scored only four goals in all competitions, a disappointing return for a player of his caliber.

Why it matters for Alexander Isak

Despite his struggles, Isak has impressed at the World Cup, scoring one goal and providing three assists in Sweden's opening three matches.

Barcelona are reportedly "closely watching" Isak, and could make a move for him as a replacement for Robert Lewandowski, who left the club on a free transfer in May.

What comes next?

It's unlikely that Liverpool would consider selling Isak for less than nine figures, given his contract still has five years left to run.

New manager Andoni Iraola will likely want Isak to be a key part of his plans next season, and a strong World Cup could be the catalyst for his fortunes to turn around.

Former Liverpool striker Emile Heskey has advised Isak to focus on coming back "super fit" and ready to take on the challenge of Iraola's aggressive system.

Isak's fitness levels were a concern for fans last season, and he will need to improve in this area if he is to succeed at Liverpool.

On 18 June, Isak played a key role in Sweden's World Cup campaign, helping his team to a round of 32 clash against France.

The 26-year-old will hope to continue his good form and help Sweden progress in the tournament.

Liverpool supporters are waiting to see Isak's aggressiveness off the ball, which was a hallmark of his game during his time at Newcastle.

A strong pre-season could lay the foundations for success under Iraola, and Isak will be keen to prove himself as a key player for the Reds.

As the World Cup continues, all eyes will be on Isak to see if he can maintain his current form and potentially attract more interest from top clubs like Barcelona.

The Swedish international has a lot to prove, but his talent and ability are undeniable.

With the right mindset and preparation, Isak could be a major player for Liverpool next season.

Only time will tell if he will stay at Liverpool or make a move to another club, but one thing is certain - Alexander Isak is a player to watch.
