We've never seen one of these before...
At half-time in the plum FA Cup third round game between Arsenal and Spurs at the Emirates the home side lead 1-0 thanks to a Santi Cazorla goal.
However, the big talking point has been this incident, which happened close to half-time. After getting into more than a few scrapes with each other, Arsenal's Jack Wilshere was on the receiving end of a bizarre reverse headbutt by Moussa Dembele.
We're not sure there was much, if any contact, but it was a very odd thing for Dembele to do, and he would surely have seen red if the Arsenal man had gone down.
Wilshere stayed up, referee Mark Clattenburg pulled the players apart and no cards were issued.
It might be worth keeping an eye on the two players in the second half, in case they clash again.
