Tottenham Hotspur manager Mauricio Pochettino has hailed his side's "important" 1-0 victory against CSKA Moscow in the Champions League.

Son Heung-min scored his fifth goal in five games to win Tuesday night's Group E clash in Russia, slotting in after collecting Erik Lamela's pass.

Pochettino told BBC Sport after the game: "That was a very important victory.

"It's important to be in the race for the next round of the Champions League. This was a must-win game, we are second in the group now, but it is still all open."

Up next for Spurs is a Premier League home game against table-topping Manchester City on Sunday.
