Watch: Valverde’s reaction to match referee after crunching Kang-in Lee tackle in Madrid derby

It has been a couple of days since the controversial Madrid derby, which Los Blancos lost 2-1, and discussion still surrounds some of the refereeing decisions on the night.

Jose Mourinho made it very clear after the game that the referee had cost them, even bringing out pictures of challenges he believes should have resulted in red cards for Atletico.

Fede Valverde 's immediate reaction to Kang-in Lee's controversial challenge during Real Madrid 's 2-1 defeat to Atletico Madrid has now emerged.

Footage circulating after the match shows Valverde confronting the referee following the tackle and demanding to know why Kang-in had escaped further punishment.

"Did you see it? Aren't you going to punish him?" Valverde could be heard asking the referee.

The reaction is particularly notable given what happened to the Madrid midfielder afterwards. Valverde attempted to continue despite the heavy contact around his left ankle.
