Newcastle United are aiming to bolster their defense by signing Kalidou Koulibaly. The club is ready to propose an €8 million deal to facilitate his transfer. Having previously played in England with Chelsea, Koulibaly, despite being in the later stages of his career, is seen as someone whose quality, experience, and leadership could significantly benefit Newcastle. With their defense currently showing vulnerabilities, adding Koulibaly to their ranks could provide much-needed strength. The club is also considering offering him a lucrative salary, and the outcome of these negotiations is yet to be determined.
