They'll be getting less for a 24-year-old World Cup and European championship winner with four years left on his contract than what Liverpool paid for Andy Carroll. And significantly less than what Chelsea paid for Fernando Torres who is older than Fabregas, even more injury prone and did not have more success on club level while a lot less influential during Spain's World Cup triumph (well, he was shite, basically).
It's daylight robbery by Barcelona, if the reports are true. I'm sure they cannot believe their own luck, getting a player like that on the cheap.
