It definitely has something to do with allegations made against his Son in respect of agents, transfer etc.
I think it also has alot to do with that Scouse loving twat Alan Green having a bit of a "pop" a few years ago.
He hasn't liked the BBC since we played Norwich away on an FA Cup tie in the mid 90's. Cantona got in a bit of a scuffle and the panel (Hansen, Hill etc) had a right go at United. Afterwards Sir Alex branded them a "Liverpool Supporters Club".
