Lansbury - Not a brill tackle but you see those 'take one for the team' challenges all the time and they are always a yellow unless I'm missing something.
You are.
Players with half a brain take the man whilst pretending they were trying to get to the ball.
Then you have Lansbury. It was almost assault.
You're not going to get a yellow for 'just kicking a player' from behind, with absolutely no attempt whatsoever at getting the ball. A shirt pull, for sure, but not when kicking a player.
