Alexander Isak will be "fuming" over Liverpool's apparent lack of urgency in drawing his transfer saga to a close, it's been claimed.
It is understood that Newcastle are keen to secure new strikers before considering letting Isak go.
Isak has faced criticism from Newcastle fans over his attempts to force a move, with some supporters seeming to direct a chant of "there's only one greedy b******" at him after the goalless draw at Villa Park.
He suggested that Isak's handling of the situation has left Liverpool as his only viable option, having seemingly burnt his bridges at Newcastle.
Speaking on the Fozcast podcast, Foster said: "He has to go to Liverpool, because I think that's probably the only team that will have him now.

"Isak's going to be fuming as well, because guaranteed that somebody from Liverpool has got in touch with his agent and gone, 'We want you here, hand in a transfer request or kick up a fuss and we'll sign you.' But they still haven't signed him.
"I think he just needs to take accountability for it all, and he needs to come out with a statement.
They're not really going to be willing to up their offer any more."

Anthony Gordon filled the void left by Isak against Villa, playing as a false nine, but Newcastle failed to find the back of the net.
The Magpies could still bolster their attacking options before the transfer window shuts, with Yoane Wissa and Goncalo Ramos both on their shortlist.

Meanwhile, Foster believes the hostility from Newcastle fans towards Isak will ultimately push the move over the line.
He's in the mud, he's done and he cannot play for Newcastle ever again, but he's got the required result.
"The club has seen that [fans chanting] at the end of the game and gone, 'We just need to get him sold.' It's a horrible way to go about it, but that's modern day football and it's the way that they go."
