The sight of Toby Alderweireld running with the ball would have been the highlight of Tottenham's training session on Thursday afternoon if it were not for Dele Alli stealing the show with his unusual face accessory.
Alderweireld is currently sidelined with a serious hamstring injury and is still not expected to be fit for first-team action until February, but the Belgian was spotted running with the ball in a significant step for his recovery.
However, the most noteworthy event was almost certainly the strange sight of Alli wearing a face mask that looks fit for polar exploration.
