They have succeeded with Robaldo and they know how beneficial Ronaldo's deal was,  that s the more reason they go for Lionel Messi. But to be truthful, these dudes are not in their era and such will attract little attention. Arab football bo is on the mission too develop and transform Arabic football and they want to do this by bringing in stars.  But the route they follow will only end them in a temporary achievement.  I think the best way they can work close to their ambition is bringing in more European your stars and giving them long term deals, other than paying extravagantly on aging stars who are already out of their football time.
