The new year began horribly for Western Sydney Wanderers with the club forced to deal with yet another fan walk-out on top of their poor A-League form, after their active supporter group stormed out midway through their 2-0 defeat to a 10-man Melbourne City.

The entire Red and Black Bloc walked out of ANZ Stadium in protest of their team's insipid first half performance with several members rushing to the tunnel to deliver a verbal spray to the Wanderers' players and coaching staff. Speaking after the match, Wanderers coach Markus Babbel even empathised with the fans who booed them at half-time.

"What can you say? They like to win, they want to see that we win," he said. "If you are 2-0 down to half time then of course they are not clapping their hands and very euphoric, this is normal. In Europe this is exactly the same."

Shortly after singing chants of support, the RBB abandoned their post and missed what could have been an impressive comeback for the Wanderers, had it not been for an incredible man-of-the-match performance from Melbourne goalkeeper Eugene Galekovic.
