The Liverpool sensation was present as Calvin Harris performed on the party island before thousands of people.

And he was accompanied by fellow Premier League stars Marcus Rashford, Kevin de Bruyne, and Nathan Ake from Manchester United and Manchester City, leaving some fans baffled.

One wondered what Roy Keane, who is infamous for disliking cordial relations between rival teams, would have thought if he had seen the post.

After Calvin Harris posted photographs of himself performing alongside football superstars, they were quickly shared on social media.

One supporter responded, “Don’t let Roy Keane see this!”

With a sad expression emoji, this fan tweeted, “With the enemies.”

However, not all of the responses were negative, with one person commenting, “Calvin Harris bringing together Manchester United, Liverpool, and Manchester City fans in one post.”

Van Dijk was out celebrating his 32nd birthday prior to returning to Melwood for training.

Jurgen Klopp was able to rally his team at the conclusion of the previous season after a lackluster year.

However, it was not enough to propel Liverpool into the Premier League’s top four as they finished fifth.

It signifies that Liverpool will participate in the Europa League for the first time since 2016, when they finished second to Sevilla.

Having won the Champions League in 2019, they are among the favorites to win the competition again in 2020.

Liverpool have already reinforced in this transfer window by acquiring Alexis Mac Allister from Brighton and Dominik Szoszblai from RB Leipzig.

Manu Kone and Khephren Thuram have also been linked with moves to Anfield.
