Vertonghen was hurt playing for
Tottenham against AjaxDefender felt he had to play with contract nearing endA blow to the head in the
Champions League semi-finals last year left Jan Vertonghen dizzy and suffering from headaches for nine months, and ruined the last season of his contract at Tottenham, the
Belgium international said.
The centre-back, who left Spurs for Benfica on a free in August, was involved in a sickening collision with his teammate Toby Alderweireld against Ajax. He had concussion symptoms for months, and was left fearing every coming together in training or a match.
