The thing is that if we don't sort RvP's contract situation out rather sooner than later, we might as well get into a situation when RvP goes at the end of the contract and we'll get fuck all for him so to get any of Kaka, Higuain or Benzema as a part of the deal wouldn't be too bad. Letting him go for free is something I'm quite sure we won't allow to happen, just as we didn't in the case of Nasri. We're talking about 25mils here and that, considering our policy when it comes to money, is a lot of money to let go.
That said, he really is that special but I'd rather have a new striker (a good one for that money) who can score half of the goals RvP did than nothing and being relied upon the likes of Chamakh, Park, Bendtner or who we are going to end up with.
