He's a very very good player. Always has been. Its not that huge a surprise that he's starting to show that potential again.
The obvious taint for many is he came from Stoke, and why was he there in the first place, if he's that good.
Without tracking his career that closely in all honesty, and just trying to use common sense.......he was massively sought after as a 20yr old as we know and for good reason at the time and joined Bayern as one of the best young players in Europe. Things didn't work out there, went to Inter, another big team. Things didn't work out there.
Maybe he was just stung one time too many by the big clubs at the time. He was only 22/23 and it was maybe just too much, too soon, and not the support network at those clubs he needed to thrive under.
Mark Hughes was at Stoke at the time and to be fair, he had some decent players there at the time, playing decent football.
And he probably sold a good project to Shaq and gave him a bit of the love and arm around the shoulder he probably needed for a lad that age.
I don't think Stoke was necessarily the wrong move for him, but he possibly stayed there a little too long.
But who are we to complain? As a result, we've got a genuinely brilliant player at a knock down price, and who has grown up and matured brilliantly over that time, which he wasn't afforded at Bayern or Inter, and who is ready again to step back into the big team arena, that bit more experienced and savvy.
Got a lot of expectations about this lad, but shocked at what I've seen so far is not one of them.
