This is according to talkSPORT, who also claim that such an enormous price tag is unlikely to put off the Catalan giants as they go off in search of new recruits this summer.
Thanks to a two-window transfer ban handed down by FIFA earlier this month after the club were deemed to have breached rules relating to the transfer of players aged under 18, it looked as if any potential swoop for Luiz - as well as moves for any other prospective targets, for that matter- would have to be shelved.
However, the news that such a ban has been suspended pending an imminent appeal has seen such rumours resurface, with Barcelona believed to be back on the hunt for Chelsea's maverick Brazilian centre-back.
Former Benfica star Luiz has forged quite a reputation in the Premier League since arriving at Stamford Bridge from the Primeira Liga in 2011.
While he is an excellent performer on his day, the 27-year-old - who will be hoping to play a significant part in Brazil's World Cup campaign on home soil this summer - has a tendency to throw caution to the wind on the odd occasion which has evidently led some fans to consider him as somewhat unreliable.
Capable of occupying a role in the heart of defence or as a holding midfielder, Luiz - providing they could suitably clamp down upon the more unappealing aspects of his game, of course - would certainly fill a notable void at Barcelona.
With long-serving captain and stalwart Carles Puyol set to leave the Camp Nou at the end of the current campaign, the reigning La Liga champions appear in rather desperate need of defensive reinforcement.
Whether they would be content to give in to Chelsea's exorbitant demands in order to push through a deal while they still have the chance, however, remains to be seen.
