Bale obviously isn't happy with lack of playing time - but, hey, he's made his own bed - RM sign (or try to sign) the best players at each and every position every summer window. Not playing... well... you're up against world class competition and you need to impress the ownership, the manager and the fanbase - or else you're out.
My guess is that Bale remains at RM next year off his spectacular CL final performance; RM will make some vague promises about increased playing time.
Meanwhile next season - who knows what transpires... Bale gets injured?... RM sign some WC darling they feel compelled to play ahead of Bale?... or Bale becomes a preferred regular starter.
