I'm in the middle of it - all my wife's family, both in the Uk and here support Millwall. I used to live in SE London & Neil Harris is something of a legend. Plus of course the Millwall slogan is "Everyone hates us but we don't care". I'm so glad I support the Imps - keeps me neutral.
Lived in SE London myself , from an early age till me mid 20s . Spent many a Saturday afternoon at the Den, mid 60s to mid 70s . Interesting times , especially a cup game against Ipswich , late 60s . Neil Harris is certainly a legend the area , I think he will do well . Hope so anyway .
