Alexander Isak has not been named in Newcastle's squad for their pre-season tour of Asia as speculation over his future continues to grow.

On Saturday manager Eddie Howe said the 25-year-old striker would "absolutely" be part of the squad for their games in Singapore and South Korea.

The Mail reported, external that Isak has told Newcastle he wants to explore a move away this summer.

BBC Sport has contacted Newcastle for comment.

A source has told BBC Sport that Liverpool are still interested in signing Isak.

Newcastle have selected a 30-man squad but said Isak "misses out with a minor thigh injury".

The Sweden international scored 27 goals in 42 appearances in all competitions last season.

He was left out of Saturday's 4-0 defeat at Celtic as Newcastle began their pre-season fixtures.

This week Liverpool signed Eintracht Frankfurt striker Hugo Ekitike - whom Newcastle bid £70m for - for an initial £69m.

Newcastle have maintained that Isak is not for sale and Howe said at the weekend he remains "confident" the player will be at the club at the start of the season.

"It's difficult for me to give 100% clarity on any player," Howe said after the Celtic game.

"Alex is happy at Newcastle. He loves the players he plays with, the staff, the team and I've never had any issue with him."

Meanwhile, Newcastle defender Lewis Hall, who has not featured since February with a foot injury, has been included in the tour squad.

Newcastle face Arsenal on Sunday in Singapore before travelling to South Korea to play a K-League All-Star team on 30 July and Tottenham on 3 August.
