I'm sure this is why Barcelona allegedly prioritised his pursuit this past summer, it was only a matter of time he'd arrive on the mainstream radar. Or maybe the board gambled on Ajax failing to qualify for CL and capitulate to the lowball offer they reportedly made. Overmars publicly claimed he was not for sale under any circumstances and then after the deadline said Barcelona failed to come with a serious offer which would suggest the board screwed the pooch. Anything could happen now I suppose if crazy money enters into it
He's a glorious talent though that will bring joy to fans of his next team. De Jong was the one player I really hoped would be tied down this summer, hope we'll have another shot in getting him to play at Barcelona. If not, hope it's City
Considering City & Spurs reportedly had bids rejected last summer, plus Barcelona's rejection, I wouldn't say he's only just now arrived on the mainstream radar.
Could well be like Mbappé where everyone tried to sign him the summer before for half the price but got rejected.
