Brighton winger Anthony Knockaert has no doubt Kyle Walker 'headbutted' teammate Alireza Jahanbakhsh during their FA Cup semifinal defeat to Manchester City.

Seagulls boss Chris Hughton insists the City fullback should've been sent off in the first-half.

And Knockaert said, “I think it's definitely a headbutt and it should have been a red card.

"But the decision was made, and we have to respect that. I can't say that it would have changed the game, and even with the game as eleven against eleven we played really well."
