The kick out is the bit that could have landed him in trouble especially if the Danish player took a tumble (debatable he meant it but it's one of those that if a ref gave it then VAR wouldn't over turn it). It's one of those small things that cause zero harm but that could get a red card. A bit like Beckham in 98 or Rooney in 2006.Probably a yellow but it seems like the ref handled it well.... Its not like he used his head or punched the guy in the face...
Mount did something similar earlier in the season against Man United: https://www.givemesport.com/1654749...ge-emerges-of-mason-mount-kicking-out-at-fred
