Tottenham have not won at Stamford Bridge since February 10, 1990.
Harry Kane was not even born when Gary Lineker's header sent Spurs on their way to a 2-1 victory over Chelsea. When the two teams meet on Super Sunday, it will be 28 years and 50 days since that success - meaning Tottenham's 25 visits to the Bridge without a win is the worst run of its kind in Premier League history.
In fact, there have only been seven instances in top-division history of teams having longer away runs without a win against a single opponent with Stoke's 54 visits to Liverpool without a victory (1894-present) leading the way.
So, as Mauricio Pochettino's men try and end over a quarter of a century of hurt, we've put together a quiz to get those brain cells working on the subject in hand.
