The Swedish striker, who hit 23 Premier League goals last season, has been the subject of heavy transfer speculation this summer, with some reports claiming Liverpool were willing to offer £120million for his services.

It has now been revealed, though, that Isak is exploring his options.

Isak has three years left on his contract, meaning Newcastle are in a strong negotiating position. It is thought that an offer of around £150m, in conjunction with Isak’s desire to move, would be difficult for Newcastle to refuse.

The Reds could add yet more forwards should Luis Diaz and Darwin Nunez leave this summer.

Al-Hilal are also preparing a significant offer for Isak, though the player is not thought to be keen on a move to the Saudi Pro League.

Newcastle are now exploring striker options, having missed out on deals for Ekitike and Joao Pedro earlier this summer, with the latter opting to join Chelsea.

“All I can say is Alex is happy at Newcastle, he loves the players, the staff, the team.

“I’ve never had any issue with him and I’m confident he’s going to be here at the start of the season.

“We have a few of those players who are irreplaceable. Your top players are so hard to find, so hard to recruit, and so hard to develop. So when you have them, you need to treasure them. Of course we’re desperate to keep him as part of our team.”
