Man U's Ashley Young gets mouthful of bird poop during match (VIDEO)

Soccer fans around the world were left gagging in disgust after footage of a white foreign substance landing in the mouth of Manchester United midfielder Ashley Young went viral.

Film evidence points at a bird being the likely culprit, although the mystery substance also resembled spit, meaning Young may have caught a stray loogie as the Red Devils fell, 2-1, to Swansea in Week One of the Premier League.

And that would have to be some magic loogie.

Good luck probably never tasted so bad.

Man U's Fellaini investigated for spitting on injured City opponent (VIDEO)

The FA have confirmed they are looking into the video footage which appears to show Marouane Fellaini spitting at Pablo Zabaleta's face during Tuesday's match between Manchester United and Manchester City.

The Man U midfielder was carded by referee Michael Oliver for a flagrant first-half elbow to the face of his City opponent during the Manchester showdown.

However, while Zabaleta rolled around on the pitch, Fellaini appears to aim a loogie at the Argentine immediately after being shown the yellow card.

A flop and a sop.

The FA could now look into this incident in much the same way as they did when retroactive punishment was on Hull City's George Boyd's spitting incident earlier this month.

Boyd was subsequently banned for three matches despite appealing the charge. 

Here's Marouane's original infraction before lobbing the gob.
