Manchester United has come a long, long way since their humble beginnings as a works team for the Lancashire and Yorkshire railway depot back in 1878. Riding out the vagaries of fortune over its first 130 years, 'Man U' has done so much more than simply keep pace with the growth of the global game. It has risen all the way to the top to become arguably the most popular club in the world and its estimated supporter base of more than 330 million fans accounts for almost five percent of the planet's population. We Are United: an unauthorized story on Manchester United will take viewers on a rollercoaster ride through the peaks and troughs of the Man U story - from the second division struggles of the 1920s and the Post-War glory days of Matt Busby's reign to the heart-rending tragedy of the Munich Air Disaster and the long haul back to the top with the help of Bobby Charlton and the sport's first superstar, George Best.
