Chelsea are understood to have had an eye on Luiz since last summer and then again began assessing the feasibility of a move for him in December, with discussions and internal evaluations taking place over the past month.
Those conversations have centred on a potential loan deal that would see the Brazilian arrive at Stamford Bridge for the remainder of the campaign.
Luiz is currently on loan at Nottingham Forest from Juventus but the situation could be restructured to facilitate a move to Chelsea, should all parties reach an agreement.
Sources indicate that negotiations have progressed positively, with confidence growing heading into the weekend that a deal could be struck. Greater clarity around the deal is expected very soon.
Rosenior believes Luiz could be an ideal fit for his system, feeling the midfielder would add both quality and depth to a Chelsea squad aiming to compete on multiple fronts.
With domestic and European commitments about to pile up, the manager is keen to bolster his options in the centre of the pitch.
Chelsea have relied heavily on Enzo Fernandez and Moises Caicedo in midfield so far this season. While the pair provide a strong foundation, there is an increasing need for additional support to help manage the physical and tactical demands. The addition of Luiz would offer a valuable rotation option.
Luiz’s Premier League experience, combined with his technical quality and composure in possession, is viewed as a major positive.
Chelsea believe his arrival could help reduce the risk of fatigue and selection issues as the season reaches its decisive stages.
With talks ongoing, Chelsea remain hopeful of concluding a deal.
