Ange Postecoglou will "never understand" any Tottenham fans wanting their own team to lose even if it helped deny Arsenal the Premier League title.
Spurs host Manchester City on Tuesday in a match which could prove crucial to the outcome of the title race.
A win or draw for Tottenham against Pep Guardiola's side would put north London rivals Arsenal in pole position to finish ahead of defending champions City.
The Gunners currently hold a one-point advantage at the summit but have played a game more than City, who would return to top spot with victory at Tottenham Hotspur Stadium, with one game remaining.
