No it wasn't. It was more like £40m. Some idiot claimed he went for £50m and everyone ran with it despite credible sources like Sky Sports & L'Equipe suggesting otherwise.
And obscene money or not every single Chelsea fan wants him back in the team. It was incredibly daft of the club to let him leave. He's better than every defender at the club bar Azpilicueta.
See this is an interesting point, not the bit about quality of defenders at Chelsea bit more what Luiz was sold for as it seems to be a major factor when people on here try to estimate what JS is worth
So what do we know about Luiz fee? Not a lot but according to The Swiss Rambler in 2013/14 Chelsea's made £65 million profit from player sales and in that year they sold 3 players for top money.
1) Kevin De Bryne. Purchased in2012 for a £7 million and after amortisation his book value when sold for a £18million in 2014 was £2.8 generating about £ 15.2 million profit
2) juan Mata . Purchased in 2011 for £23.5 million. His value after factoring in his signing a new long term contract signed in 2012 was about £15.5 million . He was sold for £37.1 million . Meaning another £21.6 profit
So add the profit from those two deals and it's around £37 million meaning still about £28 million to be accounted for
Luiz it seems cost Chelsea about £23million when he signed in 2011. He signed a new contract in 2012 . When Chelsea sold him in 2014 I estimate that his amortised value was about £12 million spookily if you add that to the £28 million (see above)you come out at £40 million
Still a vast sum and Iknow its all back of a fag packet and I suspect that in that £65 million profit there was the odd bits and pieces from elsewhere but I suspect the £50 million fee is just not anywhere near the reality
