He didn't play the ball, but he probably could have - he goes past it to block Kev.Did Partey get to the ball first, it looked to me as if he fouled Kev and didn't touch the ball?? But I admit I've only seen it once on tv
When Ramsdale parries the ball initially, both Kev and Partey are about ten yards away, so neither one has the ball. The only explanation for Oliver is that both ran to the ball, Partey got their first, and Kev ends up kicking him instead of the ball.
