Isak is a very good player, this could've been the perfect opportunity for Manchester United to sign a quality attacker and the amount he'll want is something they could easily afford but it's not likely going to happen since they can't offer him Champions League football, this would serve as a lesson to Manchester United to do better this season so they'll be able to attract quality players next summer.
Easy!! Did I hear that right? Hehe I think it would be the opposite, Man Utd would have a hard time spending that much money on Isak because their finances are not stable at the moment, and besides, as you said, Isak wouldn't want to play if there wasn't an offer to play in European competition. What I know is that Isak will go to Liverpool and he has expressed his desire, but the problem is that Newcastle doesn't want him to go.
