The pundits were just playing it back, and I think I'm a bit happier now i've seen it explained, from the initial move from the Liverpool half to the final attack and red.
Harsh red for me. The ball took a massive skip on the first bounce and so I don't think it was a clear goalscoring opportunity denied. if you look at it again the ball is in the keepers hands about half a second after Jotta chests it.
