Newcastle United ace Callum Wilson has waded into the Liverpool refereeing controversy from last weekend.

Wilson, speaking on a podcast, talked about the elbow incident involving Liverpool star Andy Robertson and assistant referee Constantine Hatzidakis.

The assistant ref was seen elbowing Robertson after half-time of the Reds' 2-2 draw against Arsenal on Sunday.

Speaking on The Footballer's Football Podcast, Wilson stated: “Honestly, I couldn't believe what I was watching. I know everyone is human and you make mistakes, and you are having a reaction when someone is on your shoulder talking to you.

“You know like when someone is on your shoulder and you just want to shrug them off, Robertson is like a similar height, so when he has shrugged him off, he has caught him on the chin and Robertson does look shocked!

“It's a tricky one because look what happened with Mtirovic when he touched the ref in nowhere near the same circumstances. This guy has thrown an elbow! What's going on!?"
