They may be unbeaten in Premier League London derbies since January, but Tottenham's record against other capital clubs currently in the top flight is disappointing.
Spurs are unbeaten in their last four encounters with London opposition (beating Arsenal and drawing with West Ham last season and beating Crystal Palace and drawing with the Gunners this campaign) since being defeated by Palace on January 10. That result came just nine days after they'd beaten Chelsea 5-3 on New Year's Day.
They will be hoping to make it five games in a row unbeaten on Sunday when West Ham visit White Hart Lane.
Despite that run, though, Spurs' win percentage against the other London clubs currently in the Premier League (25.7 per cent) is worse than Chelsea (49 per cent), Arsenal (48.6 per cent) and West Ham (27.2 per cent). Only Palace (20.8 per cent) are below them.
Most of Chelsea's dominance comes from their record over Tottenham. In 46 Premier League meetings the Blues have prevailed in 25, drawn 17 and lost just four.
Chelsea also have winning records against West Ham (22 wins, six draws and 11 defeats) and Crystal Palace (nine wins, two draws and two defeats).
Despite Arsene Wenger's struggles to beat Jose Mourinho, Arsenal have a positive Premier League record against Chelsea (18 wins, 14 draws and 15 defeats) as well as the other three in Tottenham (18 wins, 19 draws and 10 defeats), West Ham (25 wins, seven draws and seven defeats) and Crystal Palace (10 wins, two draws and one defeat).
Tottenham have positive records against West Ham (18 wins, eight draws and 12 defeats) and against Palace (five wins, five draws and three defeats). While the Hammers and Palace are level at four wins apiece and a draw in nine meetings.
In total, Chelsea have won 71 of their 145 games (49 per cent) against the other four, drawing 39 and losing 35. Arsenal also have 71 victories out of 146 games (48.65 per cent), as well as 42 draws and 33 defeats.
West Ham have 34 wins from 125 games (27.2 per cent), with 22 draws and 69 defeats, while Tottenham have won 37 of 144 (25.7 per cent) drawing 49 and losing 58.
Crystal Palace prop up the table with 10 wins from 48 (20.8 per cent), with 10 draws and 28 defeats.
