It's an open secret that Christopher Vivell will soon be joining Chelsea. But the deal isn't perfect yet. Vivell's ex-club RB Leipzig wants a transfer fee for the 35-year-old.

This is reported by Sky, but without naming a specific sum. Despite the lack of agreement on the transfer, everyone involved agrees that the deal will soon be sealed. According to Sky, it is unlikely that Vivell's installation as the new technical director at the Blues will be announced in the coming days.

The 35-year-old was released in October after two years at RB due to “different opinions”. He previously worked for RB Salzburg and TSG Hoffenheim. At Chelsea, Vivell is to succeed sports director Marina Granovskaia and will be responsible for handling transfers and squad planning in the future.

Like Petr Cech, Granovskaia had to leave the club in the summer. Since then, new owner Todd Boehly has been working to reposition the Blues at the sporting leadership level. Coach Thomas Tuchel was also dismissed in September and replaced by Graham Potter.
