VIDEO: Jack Wilshere lucky to avoid red card after headbutt attempt

Arsenal would probably be a man down if Marouane Fellaini was a foot shorter after Jack Wilshere's attempt to headbutt the big Manchester United midfielder.

Wilshere lost his cool following a challenge with Fellaini and immediately walked towards referee Mike Dean to demand a free-kick.

As he walked away from the incident, Fellaini took offense to Wilshere's cries for a foul and began to scream at the Englishman.

That's when Wilshere snapped.

Wilshere turned his attention towards the Belgian and appeared to stick his head into Fellaini's chin, forcing the United player to look towards the referee in shock.

Dean spoke with both players, but did not issue a card.
