Lisandro Martinez found himself the centre of attention just after the hour mark for a questionable challenge at Selhurst Park.

The Manchester United defender jumped into a challenge on the edge of the Crystal Palace penalty area, winning the ball but in a two footed stamping motion.

Given a yellow card despite getting the ball, the Argentine was visibly confused about the situation.

Had he made any sort of contact with the Crystal Palace player he would certainly have received his marching orders from the referee, but should he have done anyway?

What on earth was he thinking.
