My father's good friend is Iranian. He has been living and working in Europe for 25-30 years and is now retired. He has told me that any Iraninan player who has demonstrated in any way against the leadership of Iran will be fearful of reprisals on their return home. It's a terrible state of affairs. My dad's friend is the kindest and most humble man you are ever likely to meet and worked extremely hard to train as a dentist and set up his own practice. Listening to some of what he says about the regime in Iran is quite incredible.
