'I played with dizzyness and headaches for nine months - every day there was a new impact': Former Tottenham defender Jan Vertonghen reveals the shocking details of how he played through concussion problems to earn a new contract

Jan Vertonghen has shockingly revealed that he played through concussion symptoms in order to try and get a new deal at Tottenham.

The problems started after the 33-year-old Belgian collided with team-mate Toby Alderweireld in a Champions League semi-final against Ajax last year.

Now speaking to Belgian outlet Sporza, the current Benfica centre-back - who moved to the Portuguese side on a free transfer in the summer - has revealed he continued to feel the effects for nine months and played through headaches and dizzyness to try and extend his stay at the Tottenham Hotspur Stadium.
