Great clubs always take big risks. Neymar of course is a risk. Any player with 18 or 19 years old is a risk. Villas Boas is also a risk. Paying 15m for him is a huge risk, specially when we know Roman is not as patience as many wanted him to be. Torres for 50m was a also a huge risk. He is a injury prone and never did anything worth 50m. Hiring Mourinho and giving him all the money in the world to spend was also a risk, because his record with Porto was not guarantee of success in PL or in Europe. He succeed in England and failed in Europe, was he worth that gamble ? Definitely. Neymar is a risk, but is a 40m worth risk. Plus, the fact that Real, one of the greates clubs in the world, is willing to pay that much for him, its because he is woth 40m. Thats how market works. Paying 40m when no one else was interest is not the same when you know there are other clubs offering that price.
