The 23 year old has enormous talent & pace, speed to run down the wing, a position he is playing now more after starting his stroll down Football fame as a left-back. The endeavour of getting Bale to Madrid will not be easy at all, unlike ex-team-mate Modric, Bale has no intention of rebelling & at this point the only element of persuasion is cash, around 50M€ it is speculated in Football circles.
The Madrid strategy is clear, Bale can fill in if Marcelo or Cristiano Ronaldo are out of action due to injury. However, dark rumours also suggest that Real Madrid maybe rethinking seriously on whether to renew the contract of star player Cristiano Ronaldo. It is still a "dirty" rumour, but if so, Bale would be an almost perfect substitute.
Still a long time away from next summer, but we will keep a close eye on things in this interesting front.
