I dont think because people didnt like the fact a bloke on £15k a week who turns round and says how badly he is treated and wont play again (then doesnt apologise) means they arent decent supporters.
I dont really care about what players do off the pitch that much, with Saido he has had many off the field discretions but i dont remember fans booing him or hurling abuse, i dont think the fans love him like say a Astle, Regis, Taylor, etc but i think thats because he doesnt come across as a particulary likeable person (what we see) and its hard to idolise modern day footballers in general.
Personally i didnt boo him but didnt applaud him when he came on, but doesnt mean i dont support the Albion, i will cheer any goals he scores the same as i would any player but i wont give too much respect to a bloke who shows such little respect in return.
