Haaland needs to get used to the pressure. Wherever he goes, it is already clear that it will be a top club and there the pressure on him (in terms of expected results) will be constant. However, I support him in that he openly declares some problems - this will be a good signal for those who put pressure on him to stop their actions.
Haaland is young and haven't had any prior experiences in major club so yeah can understand him being unable to handle the pressure. But yeah it is also true that this is normal but Dortmund also shouldn't force him like that. He earlier send out signal one or two year ago when asked about the next club and he said that he has contract with Dortmund right now and he respects the club so won't get away suddenly. I think his plans would have eventually have been out if they would have provided him contract extension- and Haaland accepting that or/rejecting that would have eventually indicated about his plans about the future.
Yeah good point that coming out public could possibly stop this pressurizing on him.
