Tottenham's Europa League campaign continues on Thursday with the one of the longest away trips in football.
Spurs lead Group J but must defend that position in Azerbaijan when they take on Qarabag.
A win will guarantee their progress to the knockout stages, but the looming Premier League clash with Chelsea puts this match in an interesting context.
Mauricio Pochettino must balance the competing interests of Spurs' domestic and European campaigns but will almost certainly err on the side of Sunday's London derby.
Qarabag surprised Spurs earlier in the season when they took an early lead at White Hart Lane, but Heung-Min Son and Dele Alli combined with Erik Lamela in an excellent showing to secure a 3-1 win.
