Son Heung-min continued his superb recent form to give Tottenham the first win of their Champions League campaign at CSKA Moscow.
The South Korean scored his fifth goal in five games to win the game, slotting in after collecting Erik Lamela’s pass.
Spurs were sloppy in their opening-game loss to Monaco but were better in an entertaining game in Russia and could have won by more.
Dele Alli also hit the crossbar with a fierce 20-yard strike.
Spurs, who travelled to Russia without Danny Rose, Eric Dier, Mousa Dembele, Moussa Sissoko and Harry Kane, had a couple of scares but deserved their win and can now head to face German side Bayer Leverkusen – who drew 1-1 at Monaco on Wednesday – with greater confidence.
Son had a disappointing debut season for Spurs after joining the club in summer 2015 for a reported £22m from Leverkusen, scoring only eight goals in 41 appearances.
But he has hit the ground running this campaign, shouldering the goal-scoring burden for his side over the first few months with crucial strikes.
His input has become even more important as Harry Kane struggles for form and fitness and the England striker’s current understudy Vincent Janssen strives to turn effort into impact.
Son followed up his two-goal displays in the league victories at Stoke and Middlesbrough with the winner on Tuesday – another neat finish that squirmed under the outstretched hand of home keeper Igor Akinfeev.
The 24-year-old could have made a hat-trick of braces for the season to ease Tottenham’s nerves but after turning well in the box his shot was blocked.
