Chelsea have cut all ties with new Hertha Berlin signing Daishawn Redan.
BILD says Chelsea did not include any buy-back clause in the deal.
Redan is a highly rated player and the decision to not include a first-option buy-back clause could end up costing Chelsea millions if he goes on to reach his potential.
Redan, who was tempted by the move to Germany with the promise of regular first-team football, excels in the Bundesliga, he would now be free to move to any big European club.
After sealing his move to Germany, Redan said: “I'm happy that the transfer to Hertha BSC has now gone through. I can't wait to get underway."
