The “Liam Rosenior Effect” is in full swing at Stamford Bridge, and the Blues are now reportedly ready to test Real Betis’ resolve with a substantial bid for Brazilian defender Natan.
The Rosenior Era: Five Wins in Six
Since replacing Enzo Maresca, Liam Rosenior has transformed Chelsea’s fortunes, securing five wins in his first six matches. However, to sustain this momentum, the English manager has identified the heart of the defense as a priority area for improvement.
According to journalist Pablo Oliveira, Chelsea’s primary target is now Natan, the 24-year-old former Flamengo and Napoli man who has become a revelation in Spain this season.
The €40 Million Bid

Reports suggest that Chelsea are preparing a formal €40 million (£33.5m) offer to bring the Brazilian to London before the January window slams shut. While Natan’s market value is currently pegged at €20m by Transfermarkt, his importance to Manuel Pellegrini’s side means Betis will likely demand a premium.
Betis only recently made Natan’s stay permanent, paying €9 million to Napoli after a successful loan spell. Selling him now for €40m would represent a massive financial win for the Seville-based club, though it would leave a significant hole in their backline.
A Rising Star: From Flamengo to the Bridge?
Natan’s journey to the top has been meteoric:
- Youth: Developed at Flamengo’s famed academy.
- Breakthrough: Stood out at RB Bragantino before moving to Serie A (Napoli).
- La Liga Dominance: Has clocked 28 appearances for Betis this season, earning a reputation as one of the most physically dominant and technically gifted center-backs in Spain.
If the deal goes through, Natan would face stiff competition for a starting spot at Chelsea alongside the likes of Wesley Fofana and Trevoh Chalobah.
Player Profile: Natan (Real Betis)
- Age: 24
- Nationality: Brazilian
- Contracted until: June 2030
- Playing Style: Aggressive in the air, excellent recovery speed, and comfortable playing out from the back.
