The Crystal Palace midfielder had been attempting a volley and, with his eyes on the ball, clattered into the England international.He got away with only a booking, but the tackle got worse with each passing replay. It was bad enough that Saka had to be substituted with what appears to be a calf injury.Halftime analysis showed the full extent of the tackle. Questions were asked of why the VAR did not advise center referee Mike Dean to take another look at whether a red card was deserved.Further VAR talking points came in the second half with both of Crystal Palace's goals. There were calls by the Arsenal players that both Partey and Lokonga were fouled in the build-up, and the second case, in particular, had strong merit.#4 Crystal Palace undone by defensive lapse in the final minutes yet againCrystal Palace conceded an injury-time goal against ArsenalCrystal Palace gave as good as they got against Arsenal.
