Isak has attracted interest from Al-Hilal and Liverpool, with both clubs reportedly lining up moves for the talented forward. If Isak is unable to be persuaded to stay at Newcastle, the club may turn to Sesko as a potential replacement.
Sesko, who signed a new contract with RB Leipzig last year, has a deal that runs until 2029. His new contract also included the removal of a £55m buyout clause. While RB Leipzig are willing to sell Sesko if he chooses to leave, the club is likely to do so at a realistic price.
