There was one particular moment during Harry Winks' coming-of-age performance at the Bernabeu a fortnight ago that was largely inconsequential, but said so much about Winks' maturity and composure.
In the 52nd minute, Tottenham regained possession from Real Madrid in their left-back zone, partly thanks to Winks pressuring Raphael Varane. The ball fell to Jan Vertonghen, and so Winks took the opportunity to glance over his right shoulder, scanning the pitch quickly. As Vertonghen played the ball towards him, Winks again looked over his right shoulder, before playing a first-time ball to Toby Alderweireld, and then looking again, this time over his left shoulder.
