Inter-Juve, slow motion: between Dumfries and Alex Sandro a penalty shot. Is it from Var?

When Dumfries ‘right foot hits Alex Sandro’s left leg at 41’, for the referee Mariani everything can flow, there is nothing, and therefore it is assumed that he has also seen and evaluated the position of the leg hit by Juventus. But the Var (Guide), at that point, recalls him: the ingenuity of the Inter player in hitting the Bianconeri’s limb already occurs inside the area and leads to the assignment of the penalty kick. But the ignition of the “on field review” is under discussion: does it imply the clear and evident error? An oversight of the referee who did not notice, perhaps deceived by Alex Sandro’s right foot well outside the area, of the contact over the line? In the rest, Mariani was well positioned in the 48th minute of the first half when a cross from the right hits the heads of Dzeko and Chiellini and not the arm (however high) of the Juventus defender. Regular Dzeko scores.
