Arsenal fans fume after refs miss headbutt on Stephan Lichtsteiner

ARSENAL fans vented their fury on social media after Sporting Lisbon star Sebastian Coates escaped unpunished after his headbutt floored Stephan Lichtsteiner.

The Gunners’ 11th victory in a row was marred by bitter drama at the end as Uruguay defender Coates approached the Arsenal full-back and sent him flying.

TV cameras caught what looked a blatant assault from Coates, whose blunder had handed Danny Welbeck a deserved 77th minute winner in this Europa League clash.

But Arsenal supporters were baffled at how officials seemingly failed to spot Coates thrusting his head into Lichtsteiner’s - in the middle of the penalty area.

One fan tweeted: “Wonder what match @europaLeague officials are watching where they completely miss Coates headbutt on @lichtsteinerSte.”

Another said: “Tough game for Arsenal, but we did it. 5 referees, but still couldn’t spot a headbutt from Coates on Lichtsteiner. Job done lads.”

Supporters also called for TV evidence to land Coates in hot water.

One argued: “Surely a retrospective ban for Coates@ Definite headbutt on to banned after TV footage is studied. Definite headbutt on Lichtsteiner.”
