Jose is right, it has been appallingly quiet recently. It's embarrassing to have small away fan contingents like there was against Huddersfield and Bournemouth out sing, chant, and cheer a stadium of 70,000 Utd supporters. I was at a Palace game recently, which is a ground of 20,000 and the noise there was immense, produced by a ground a third the size of OT. They have a drum section that leads all the chanting and produces noise and it was great. Looking forward to going back there for the Utd match in a few weeks.
At OT there is a large contingent of fans who are there for one game, or their first time at OT, and they don't know the chants so maybe we can do more to let people know what the chants are. Put them in match day programmes or have some people who lead the chants, like they do at Palace.
