A number of Leeds United supporters have been reacting with anger on social media to Brentford midfielder Sergi Canos’s apparent headbutt on Ezgjan Alioski.

The Spaniard appeared to aim a headbutt at the Whites winger during a scuffle in the Brentford dug out during the teams’ 1-1 draw at Elland Road on Saturday.

Also footage doing the rounds of of Canos appearing to aim a headbutt at Alioski in Brentford's dug-out (during the scuffle). A few things today which might keep the FA busy on Monday morning. #lufc — Phil Hay (@PhilHayYEP) October 6, 2018

However, there was no action taken against the former Liverpool man, and the Leeds support were unimpressed, to say the least, with the referee’s inability to spot Canos’s offence.

It is a clear head butt from Canow. Real coward and also as he did it not facing Alioski. Terrible conduct — Stephen (@Krishna2323) October 6, 2018

Be interesting what punishment @EFL gives Canos of Brentford FC for head butting Alioski of @LUFC when he tried getting the ball back #lufc — Mike Hayward (@SussexWhite) October 6, 2018

So Canos should be banned for violent conduct, Watkins for successfully deceiving a match official and that ref should lose his job. But I'm expecting none of that and Jansson to get banned for calling the efl out. #lufc — James (@JHlufc3__) October 6, 2018

@LUFC_WYP ermm how do I report an assault?? When it was captured on TV can a 3rd party do it or do it have to be the person been assaulted?? Or can you just take action against canos? #bfc #lufc ???????. — Craig (@CraigLUFC77) October 6, 2018

@FA @SkySports Nothing going to get done about Canos head going into alioski when Sergio Canos isnt in the game and alioski went to get the ball? Or is it just Leeds players that get done after the game via camera? @LUFC pic.twitter.com/B0KvI0si7W — Majid Din (@MAJ_JD) October 6, 2018

@efl @FA I take it there will be retrospective action taken for the headbutt by Sergi Canos? Disgusting. #LUFC pic.twitter.com/BpI9ErK6fQ — Cockney White (@cockney_white) October 6, 2018

OPINION

It’s easy to see why the Leeds fans are so riled up by this. There’s clear video evidence captured by Sky Sports that shows Canos head butting Alioski in the back of his head. For the referee to miss that was pretty bizarre, and the fact that none of the other match officials saw it either beggars belief. Brentford produced an excellent performance against Marcelo Bielsa’s side, but will feel a bit let down by some of their conduct. It was a good game of football that was marred by a few poor incidents and a woeful performance from the referee. Headbutts are uniformly considered violent conduct so the FA should hand Canos a three match ban retrospectively. Whether they do or not remains to be seen, and the Leeds supporters seem to be somewhat dubious on the possibility of it happening, but Canos certainly deserves some sort of punishment for his actions.
