Is this handball that’s being mentioned Rice’s from Partey’s mistake? From the angle on the Arsenalist link above I’m not seeing a handball at all. His arm is moving in a downward motion and his torso is moving forward, and the ball clearly bounces forward from wherever it makes contact. If it was the arm/hand, then it would have moved down.
Maybe there’s another angle that shows it better that I haven’t seen, but it’s definitely not a handball on that link
