English referee Mark Clattenburg is at the centre of controversy yet again after awarding a debatable penalty during the Red Devils' embarrassing defeat

English Premier League giants Manchester United looked to have gotten their season back on track after marching to a 3-1 lead against newly-promoted side Leicester City, in the 57th minute.

Coming inches to back-to-back wins, and claiming their first three points from an away counter, Louis Van Gaal's side collapsed to an unbelievable 5-3 loss at the hands of the Foxes.

A 62nd minute penalty from David Nugent, and a 64th minute goal from Argentine midfield veteran Esteban Cambiasso brought the home side level, before adding another two goals prior to the final whistle, leaving the Red Devils faithful disappointed.

However, the Manchester United fans were left fuming at referee Mark Clattenburg. A famous official, for all the wrong reasons, Clattenburg spot kick decision was controversial.

David Nugget was brought down in the box by Brazilian right-back Rafael, but the 24-year-old defender appeared to be fouled by the Leicester City attacker prior to the penalty, something Clattenburg failed to pick up on.

The English referee was later blasted on Twitter, as he went on the award Nigel Pearson's side yet another penalty for Jose Ulloa's second goal of the day, Leicester City's fifth, giving young Red Devils defender Tyler Blackett a red card.

The pressure now further mounts on Dutch manager Louis Van Gaal. Brought in to rebuild the club after David Moyes' disastrous reign, the former Barcelona boss has seen his team fallen to their third loss this season.
