Norway coach Stale Solbakken and team manager Brede Hangeland made those comments in the aftermath of their nation's 1-1 draw with Morocco.

Brahim Diaz put Morocco ahead in the eighth minute at Sports Illustrated Stadium in New Jersey, but Martin Odegaard equalised 15 minutes from time for Norway.

That was Norway's final public friendly ahead of its Group I opener against Iraq, on 16 June, though it was due to face Scotland behind closed doors on Tuesday, with both teams being based in North Carolina.

However, the Norwegian Football Federation announced that the game has been called off, prompting Solbakken to deviate from his plan to rotate more heavily against Morocco.

Scotland boss Steve Clarke subsequently said the game "wasn't worth the risk" after a couple of his players sustained injuries, but senior figures in the Norway camp were not convinced by that argument.

"It is unprofessional of Scotland," Solbakken said. "It is unprofessional that the coach has not called me, that they use the team manager and call and say it after we have finished training.

"I don't think the injuries they're blaming came from the last training session. That's not the case. It's disappointing. It's unprofessional.

"But we have to live with that. That's why we adjusted a bit in the game."

Former Fulham centre-back Hangeland echoed those sentiments, saying: "It is embarrassing to cancel it a couple of days before. 

"We can't do anything about it. We just have to forget about it and make the best of it. 

"But there has been a lot of organisation, agreements and gentlemen's agreements and then suddenly they don't want to. I think that was weak, so to speak."

Norway also takes on Senegal and France in the group stage, while Scotland faces Haiti in its first Group C match on 13 June.
