Red Bull Leipzig forward Christopher Nkunku reportedly had a 'secret medical' with Chelsea this summer ahead of a potential move before the start of the 2023-24 season.
The Frenchman underwent tests in Frankfurt in August, with a Chelsea orthopedist present, according to German outlet Bild, as the Blues look to steal a march in the hunt for one of Europe's hottest properties.
Nkunku already has six goals and an assist this season after a breakout campaign in 2021-22, which saw him score 20 goals and make 15 assists in the Bundesliga.
