Yeah, its pretty clear that 30-33 is the decline of players, very rarely the peak, as seen by the quite shocking decline of players going for any type of money in that age range. In the top 50 list of most expensive players who have turned 30, something like 80% are 30, 15% are 31 and hardly anyone is 32+ except Ronaldo. Ronaldo is an extreme outlier here, being 13 times more expensive than anyone else who have turned 33. Vidal with a year left on his contract is right up there among the most expensive ever at 31+. With a year left, the price usually falls to half. So there is nothing suspiciously low about the fee at all. This should also make us realize that we can not in any way count on oil clubs or Chinese clubs to offload our players once they age.
