John Terry has taken to social media to reveal his own strange superstition involving the plug sockets at Chelsea's Cobham training ground.
The former Chelsea skipper spent 17 years on the books at Stamford Bridge, and was their most decorated captain and leader winning five Premier Leagues and a Champions League title.
He would make 717 appearances for the Blues, scoring 67 goals in the process, as well as earning 78 international caps for England and a stint as captain of the Three Lions.
However, as with most of the greats of the game, Terry has revealed that he has a number of superstitions that he has observed throughout his career.
