Also a former Newcastle player, Hutchinson was unimpressed by Isak behaviour as he forced his way from the Toon to Liverpool over the summer.
He said, "There's no doubt about it. Alexander Isak should have behaved more professionally this summer, and now he's paying the consequences. He should have seen the bigger picture.
"He shouldn't have been so selfish and trained with Newcastle, even though he knew he was going to leave. If the transfer hadn't gone through, he would have had to be fit to play for Newcastle.
"Isak's behavior was unprofessional and naive. I think his agent advised and managed him very poorly throughout the summer. Generally, when you arrive at Liverpool, you have to start on the right foot. Now he has to catch up, and that's because of his behaviour."
