There's a chance that we've seen the best from Bale. The injuries he sustains are muscle strains i believe? They're sometimes caused by a players style and build. Bale is an Athlete, he's like a 200m runner, it could be because of that accelaration that he keeps getting these injuries and that could play on his mind when he is in a position to run in the way that he does. I hope that we see the Bale of old, although i have my reservations, i don't think that he'll be able to sustain the way he plays, especially with the injuries that he gets. Michael Owen relied on 20-30 yard bursts of pace but suffered terible injuries that were down to his running, he became conscious of this and stopped making those runs, in short he was never the same player.
