We asked for your views after Isak was left out of the squad. Here are some of your comments:

Gary: If these tours are all about driving commercial revenue, surely you take your star striker regardless of a minor injury?

Kevin: Concerning. I hope it is just precaution. It would be really disappointing if he does leave this summer after all the hard work last season to get into the Champions League. Lack of transfers in areas and missing out on targets isn’t making me feel any more confident for the coming season either.

Martin: Until he comes out and says he wants to leave, he is injured. Full stop.

Richard: I hope I am wrong but I do not see Isak being in a Newcastle shirt next season. I think the club will sell, but the way transfers have fallen so far, I worry that we will not be able to recruit to the level we need.

Bob: Is “thigh injury” just an excuse and he is on his way out? Be honest – the fans deserve it. If we go into the season with one striker who is not proven we have got no chance.

Kevin F: Isak had thigh problems end of last season so this is nothing new. But if it is true then it should have been sorted out by now. I just hope it’s nothing more.

Mark: I think he is unsettled and can see him moving to another club. If he does, we desperately need other players up front. I hope I am wrong.

Richard: Something isn’t quite right. What really needs to happen here is Isak to come out and say he is staying and that’s it, or we are going to have speculation all the time. Is it his agent fuelling the situation by saying: “Why stay? You could earn mega bucks elsewhere.”
