Jan Vertonghen is reportedly set for two months on the sidelines with an ankle injury suffered in Tottenham's 4-0 win over West Brom on Saturday.
The Belgium defender is said to have sustained ankle ligament damage in the victory, which kept Spurs within seven points of Premier League leaders Chelsea.
Vertonghen has played in all but one of Tottenham's league games this season.
And he has been key to their impressive form, serving as an integral part of a Tottenham defence that has been extremely difficult to breach.
Here, with the help of Opta, we look at the impressive statistics surrounding Spurs' defensive performance, which could well decline with Vertonghen out of the picture.
Thanks to everyone for your kind messages. Gutted to be injured but will be back as soon as I can #COYS-- Jan Vertonghen (@JanVertonghen) January 17, 2017
