Tottenham Hotspur boss Mauricio Pochettino has revealed that he substituted striker Vincent Janssen for winger Georges-Kevin N'Koudou against CSKA Moscow as he wanted more mobility in his side's attacking play.
The Argentine manager made the change in the 67th minute of the game and subsequently moved Son Heung-min into the central role previously occupied by Dutchman Janssen.
The change quickly paid dividends as the South Korea international scored the only goal of the game four minutes later to clinch three points for his side in the Champions League.
"We tried to find more mobility in our offensive position," Pochettino said
"It is for that reason we changed Vincent for N'Koudou, to have more pace down the sides.
"First touch we find the link and it was fantastic the goal. Sometimes when you change, it goes well and sometimes no."
