There was quotes in December last year from Moyes saying he wanted to have a look at him personally, so he is known to big clubs as you said, which makes your second point a bit strange as we've just seen that United may have been interested. Again, I'm not trying to necessarily change your view, but you aren't someone to make silly predictions from what I've seen so I'll keep an eye on him more in future, as currently, I'll admit I've sen nothing other than my good friend Youtube, what sort of attacking mid is he out of interest, I see he's been tagged as poor Hallalovic was with the "new messi" tag...
Let the old one retire first.
