WILL IT BE UNLUCKY NO.13 FOR TOTTENHAM AGAINST CHELSEA?

The north Londoners have not lost since the opening day of the season, but will they finally come unstuck against the Blues on Sunday... and who poses the biggest threat?
Tottenham will put their 12-game unbeaten run on the line when they host London rivals Chelsea in the Premier League on Sunday, with Mauricio Pochettino's men unbeaten since the opening day of the season.
It is 112 days since the White Hart Lane outfit last tasted league defeat - Kyle Walker's own goal at Old Trafford sealing their only loss - and they have risen up to fifth place in the table, just four points adrift of leaders Leicester City.
It is the joint-longest unbeaten streak Tottenham have managed in the Premier League era - you have to go back 30 years to find a longer run! - but it is still some way short of Arsenal's record 49-game unbeaten streak.
While Tottenham have been in stunning form this season, champions Chelsea have struggled to replicate their title-winning form of the previous campaign and currently sit in 15th place, just five points above the relegation zone.
The stats are ominous too: not only have Spurs had the most shots on target in the Premier League this season, but only four teams have conceded fewer. For Chelsea the opposite is true: only Newcastle and Sunderland have given up more shots on target, not to mention the fact they conceded five times on their last visit to White Hart Lane in January.
But the Blues will be buoyed by the fact that Spurs have endured a 5,000-mile round trip to face Qarabag in the Europa League, while in Cesc Fabregas and Eden Hazard they have two players who have tormented Tottenham in the past.
