You raise a good point here. Food is a great way for cultures to integrate and appreciate each other.
The problem with your proper muslim is that they have rocked up in a country that is built on pub culture. If you dont have a beer, nobody is going to trust you or take you seriously.
They don't sell alcohol "on religious grounds" but you can take your own booze.
Win-Win, as they say, imo.
Other clubs never came into my thoughts once I knew Arsenal wanted to sign me.
