It doesn't make a lot of sense to me either. If we really have the cash for one biggish money signing this summer, he's not the type of player I'd chose to spend it on. I'd use it to improve the spine of the team through the center, not go for a 19yo flash harry winger thats likely to be booted into the stands within the first 5 mins of most games.
From the Leeds fans I've heard describe him, he seems like the next Adama Traore, only smaller. He's not been linked to any other PL team that I can recall, so what are we seeing that none of the rest do? For sure, if he does well for us his value is likely to rocket given his age. I just don't trust our scouting team to be able to find the jewel where others can't.
