Chelsea could push ahead with a move for Sevilla star Jules Koundé if Antonio Rüdiger departs the club in January, according to reports.
The west Londoners have been working to extend the Germany international's past 2022 to avoid the risk of losing him on a free next year, but it has been reported that the 28-year-old's future hangs in the balance, with Chelsea waiting for a decision over the defender's future.
Bayern Munich, Paris Saint-Germain, Juventus, Real Madrid and Atletico Madrid have all been linked with a January move for the former AS Roma man, who is demanding a significant pay rise to further his stay at Stamford Bridge.
It was reported recently that the 22-year-old central defender will be able to feature in the Champions League if he swaps Sevilla for Chelsea in January.
The Blues believed they had struck a verbal agreement with the La Liga outfit over a fee for the defender, which is believed to be around €50 million plus add-ons.
However, Sevilla turned around and demanded an additional amount worth €15 million following Kurt Zouma's switch to West Ham, which made the European champions back out of a deal and pursue other targets.
The potential signing of Koundé had been discussed among Tuchel and the club's senior players, but Chelsea did not raise their offer for the Frenchman this summer.
It has been stated previously that the Blues will reassess the situation in January after failing to seal a move for Koundé, who will spend a third season in the Spanish top-flight.
Rüdiger has established his status as one of the first names on the teamsheet in west London since being handed a new lease following Thomas Tuchel's arrival to the club in January.
With the Germany international entering the final year of his existing deal, it remains to be seen if he will commit his future to the Blues, who have been targeting defensive reinforcements in recent months.
