I think that could cut either way. Yes he possibly would have better care and guidance nowadays, but equally his flaws may have stopped him getting to the top earlier - can't see a teenage gazza progressing in our academy.
Just about every midfield/forward in our academy now has the talent that Gazza had. He just stood out a mile at the time because his game was more about technique, dribbling and passing than it was about stamina, commitment and tackling, which was rare in England back then.
