Real Madrid, Chelsea and clubs from Saudi Arabia are keeping tabs on Napoli striker Victor Osimhen, according to the Daily Mail.Osimhen, 24, appears likely to leave Napoli in January after the club made the bizarre decision to post a video on TikTok mocking the star striker. His agent Robert Calenda slammed the move, saying the video caused "very serious damage to the player" and that he "reserves the right to take legal action" against the club. Osimhen has since deleted almost all pictures of himself in the team's shirt from his social media accounts.Real Madrid are still looking to sign a No. 9 following Karim Benzema's move to Al Ittihad in the summer. But with their incredible wealth, Saudi Arabian clubs are expected to lead the chase for the Nigeria international.Chelsea are also interested in Osimhen, although any move could be made more complicated by the incentivised wage structure that was brought to Stamford Bridge by American owner Todd Boehly.Osimhen, who scored in Napoli's 4-1 win over Udinese on Wednesday, has a contract with the Serie A champions until 2025 and the report says that a transfer fee in the region of €150 million will be required if Napoli are to talk terms.
