#1 Douglas Costa steps up to make the difference
With the game heading towards a draw and the players on the field bereft of attacking ideas, Maurizio Sarri needed to shake things up and he turned to his bench to summon Douglas Costa in place of Sami Khedira in the 70th minute.
The Brazilian is a bundle of talent and skill, but has been blighted by injury troubles in recent times which has seen him drift in and out of the Juventus starting lineup.
Against Lokomotiv, the 29-year-old did his starting chances a world of good with a well-taken goal in injury time.
He had combined well with Gonzalo Higuain in the buildup, then showed good close control and quick feet before slotting a fine finish past Guilherme to give Juventus all three points with few minutes left to play in the game.
The goal was his first this calendar year and if he can stay fit, there is no doubt that he would play a key role in Juventus' charge on all fronts this season.
