Having been to the Emirates several times but not Saturday, I concur with the reports about the dreadful home atmosphere. The big 4 all seem to suffer this problem - they all have a very large corporate/Disney tourist portion at games. Emirates is even worse due to the architecture: mid stand corporate circle ringing the entire ground, disrupting the formation of big banks of real, coordinated, singing, fans.
That and the demographic of their fan base (and any fan base now tbh) now is simply not like the seething, boiling hoards of shaven headed lads that filled the Archers cages in the 70s
