Juventus coach Massimiliano Allegri heaped praise on Sami Khedira for his prominent role in the crucial 3-1 win over AC Milan at Allianz Stadium on Saturday.
Khedira provided the cross for substitute Juan Cuadrado to restore the hosts' lead in the 79th minute before sealing three points himself with a well-taken third late in normal time.
Leonardo Bonucci had earlier cancelled out Paulo Dybala's opener and the Rossoneri looked on track to earn a point in an away match at Juventus for the first time since 2011, before Khedira helped swing the match back in Juve's favour.
The Bianconeri are now four points clear of second-placed Napoli and well on track for a seventh straight Scudetto.
"Khedira is a world-class player and he knows how to read the crucial moments of a match," Allegri told Mediaset Premium.
"That is very important as in some moments you need certain players and at others you can change and introduce substitutes who can turn it around.
"We really could have done with a player like Khedira [in the draw] against SPAL as he is so intelligent. At times he might seem slow or error-prone, but he reads the game so well."
Allegri believes the victory over Gennaro Gattuso's side serves as a message to their upcoming opponents and to title rivals Napoli who were earlier were held to a 1-1 draw away to Sassuolo.
"It was important to get back to winning ways against Milan, who are in good shape," he said. "The lads did well to bring the result home in a difficult fixture and to increase our lead at the top of the table. Wins like this send a signal."
