Spurs came into the match buoyed by Saturday's draw at bitter rivals Arsenal - a team Slaven Bilic's side pushed close in this season's Champions League play-offs.
Defeat to the Gunners saw the #Turkish outfit drop into the #EuropaLeague, where they looked set to suffer more north #London frustration until Ba's last-gasp penalty cancelled out Harry Kane's 20-yard strike to secure a 1-1 draw.
Chiriches was guilty of giving away the spot-kick with a foolish handball when trying to make amends for an initial air kick, allowing the former #Chelsea striker to finally beat Lloris.
