The young French defender is upset by suggestions that he has yet to fully recover from the operation that he underwent last year despite struggling for game time
The young Frenchman broke into Jose Mourinho's first team last season and quickly established himself as one of the most promising centre-backs in world football before being forced to undergo knee surgery at the tail end of the 2012-13 campaign.
Varane has struggled for regular game time this term under new Madrid boss Carlo Ancelotti but insists that he is not suffering any adverse effects from his injury problems of old.
"Many things have been said about my knee but I don't like jokes about my knee surgery," he remarked to AS.
"The situation is clear: I was in good hands with Dr Herve Silbert. I keep in touch with him; he did a great job.
"All is well in the joint of my right knee and I don't doubt it."
The 21-year-old sat out training this week in a bid to maintain his fitness ahead of the Champions League final later in May.
