Patrick van Aanholt insists he is fit and ready to play for Sunderland despite concerns over his heart.
Sunderland full-back Patrick van Aanholt played down concerns he was battling a heart complaint.
Van Aanholt was named to start his side's visit to Tottenham in the Premier League on Sunday before being replaced shortly before kick-off.
It was later revealed the left-back was withdrawn after "medical advice from cardiologists".
However, Van Aanholt, a six-time Netherlands international, insists there are no concerns over his heart.
"I was indeed surprised, because there is really nothing to worry about," he told Voetbal International.
