Who won the ball first? Liverpool Vs Manchester City. Jeremy Doku challenge on Alexis McAllister.

Did Jeremy Doku win the ball first or did Alexis McAllister? Hopefully this clears it up for some people. The decision by on field referee Michael Oliver was no penalty because he believed Doku played the ball the VAR agreed with the on field decision and did not recommend a review. But did Doku even play the ball?
