Ten-man Tottenham condemned Nottingham Forest to a fifth Premier League defeat in six games as they underlined their top-four ambitions at the City Ground.
Richarlison’s third goal in two games set Spurs on their way, with the outstanding Dejan Kulusevski sealing victory for Ange Postecoglou’s side, which had Yves Bissouma sent off in the 70th minute.
The result moves fifth-placed Tottenham level on points with Manchester City, although the champions have played a game less. Forest sits 16th in the table, five points clear of the bottom three.
Spurs controlled much of the first period and deservedly went ahead on the stroke of half-time when Brazil forward Richarlison nodded in from Kulusevski’s superb cross from the right.
The hosts made an encouraging start to the second period, and Willy Boly missed arguably their best opportunity to level, blazing over from just inside the visitors’ penalty area.
Steve Cooper’s side also briefly thought they had equalised just before the hour mark, but the video assistant referee correctly judged that Anthony Elanga had just strayed offside before sweeping in Neco Williams’ cross.
And two errors from goalkeeper Matt Turner sealed their fate, with the American passing a clearance straight to Kulusevski before allowing Sweden’s powerful drive to beat him at the near post.
Tottenham goalkeeper Guglielmo Vicario’s reaction save from Harry Toffolo’s point-blank late header summed up an unproductive evening for the hosts in the final third.
