Robbie Earle says Alexander Isak could reach greatness at Newcastle United.

Ex-Port Vale and Wimbledon man Earle hailed Isak, backing him as the next “black-and-white hero" on Tyneside while paying tribute to the legendary position.

“My underappreciated performer of the week goes to Alexander Isak," he told NBC Sports. “I think it's like six Premier League goals now. He started this season and got an injury so it's been a stop-start since his club-record move to Newcastle.

“Callum Wilson started the season well, scoring goals and was probably quite rightly the number nine. But I think we've always felt like that, Isak, given the opportunity, can score goals.

“He looks like a threat. He is a good runner, a good dribbler, holds it (the ball) up well and looks intelligent. Good technique, nice finishing off both feet. That first volley was a lovely finish where he controlled the ball behind him.

“He could be the next big-time Newcastle United centre-forward. A black-and-white hero for that football club, who love their strikers up there. There isn't a better position in Premier League football than a free-scoring striker for Newcastle United.

Earle also said, “When I was thinking last night, Patrick Kluivert (who Isak reminds him of).

“Remember Kluivert? He was a centre-forward, but very, very technical, (with) natural ability and can make things happen. He's had a few injuries. He's coming to English football. He's one of them just to keep an eye on, Alexander Isak."
