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.

England soccer star Kyle Walker caught inhaling 'hippy crack' from balloon at nightclub: Report

England soccer star Kyle Walker has been photographed appearing to inhale "hippy crack" from a balloon while partying with friends inside a hometown nightclub.

The 23-year-old right-back, who played for England against Moldova in Friday's World Cup qualifier, allegedly sucked in the potentially deadly nitrous oxide several times during a night out in Sheffield last June, the Sunday Mirror reported.

The controversial laughing gas, which is portioned into balloons and sold for as little as $3, is a legal but dangerous high and has effects likened to those of crack cocaine or heroin after taking a huff.

It has been known to cause users suffocation, seizures, strokes, blackouts, chronic depression and strain on the heart.  The drug is not as prevalent in US clubs as it is across the pond.

The Sunday Mirror said that Walker, who plays for Tottenham, allegedly inhaled a number of times from the balloon while out with friends on June 1. He was recovering from an injury that forced him to sit out England's friendly double-header with the Republic of Ireland and Brazil.

Walker, the Player of the Year last season, is expected to line-up against for England in Ukraine on Tuesday in a must-win World Cup qualifier.

"More and more canisters of laughing gas started appearing," said an eyewitness at the club.

"Kyle and his pals were getting well carried away with them. He didn't mind one bit that people were taking pictures."

"Hippy crack" first became popular during the 1960s, but has now become a popular legal high in British nightclubs, where it is sold for a few bucks.

The FA have declined to comment.
