Hugo Lloris' stunning saves helped Tottenham claim a 1-1 Champions League draw at Real Madrid, for whom Keylor Navas also impressed.
Mauricio Pochettino looked to have got his game-plan spot on against the holders at the Bernabeu as Serge Aurier's cross was turned into his own net by Raphael Varane (27), but Cristiano Ronaldo equalised from the spot (43) after a needless foul from Aurier.
Both teams could have won it, but were indebted to their goalkeepers Lloris and Navas who starred with some important saves.
The teams meet again in Group H in a fortnight's time at Wembley, and both look odds-on to qualify having taken seven points from their first three games.
Real Madrid: Navas (8), Achraf (7), Ramos (6), Varane (6), Marcelo (6), Casemiro (6); Modric (6), Kroos (6), Isco (7), Ronaldo (7), Benzema (5).

Tottenham: Lloris (8), Alderweireld (8), Vertonghen (7), Sanchez (7), Aurier (6), Sissoko (7), Dier (6), Winks (7), Eriksen (7), Kane (7), Llorente (8)
Subs: Rose (6), Son (6)
