Chelsea have attempted to secure an advantage in the race to sign Christopher Nkunku from RB Leipzig by arranging for the striker to undergo medical tests ahead of a proposed move, sources have told ESPN.
Nkunku, 24, has attracted interest from several top clubs including Manchester United, Real Madrid and Bayern Munich.

But Chelsea have attempted to position themselves at the front of the queue after overseeing private tests in Frankfurt a few weeks ago with a Chelsea orthopaedist present.
Reports of the test first appeared in German newspaper Bild and have since been confirmed by sources to ESPN.
Nkunku is believed to have a release clause in his contract set at €60 million which comes into effect in the summer of 2023.
