Chelsea is set to sign 18-year-old Barcelona forward Marc Guiu for €6 million, with plans to loan him out to Sevilla or Strasbourg. Chelsea has made a formal offer for Leicester City's midfielder Kiernan Dewsbury-Hall, who prefers a move to Chelsea over Brighton, despite a previous £25 million swap deal involving Jakub Moder. Dewsbury-Hall, who scored 12 goals and provided 14 assists last season, is also attracting interest from Brentford. Chelsea manager Enzo Maresca, who previously managed Dewsbury-Hall at Leicester, is keen on reuniting with the midfielder. Additionally, Chelsea has shown interest in Newcastle striker Alexander Isak, potentially involving a record fee.
