John Terry, the man himself, must also be considered.
He has had altercations with England before, including an unbacked call for Joe Cole to figure in the national team more regularly and with personal issues with teammates including Wayne Bridge.
But not until this season had he really looked in any danger of turning his back on England.
A long-running row involving QPR defender Anton Ferdinand started in October 2011, when Terry was accused of racially abusing Ferdinand.
The case dragged on for just shy of a year as Terry was taken to court and cleared of making a racist insult, then charged by the FA and found guilty of "using insulting words which included a reference to Anton Ferdinand's colour or race" (h/t the Guardian).
Just days before the announcement and subsequent fine and suspension was imposed on Terry, he announced his retirement from playing for England. Terry made clear his reasons for the decision:
I am making this statement today in advance of the hearing of the FA disciplinary charge because I feel the FA, in pursuing charges against me where I have already been cleared in a court of law, have made my position with the national team untenable.
It was clearly the FA was where his disappointment and anger were directed at, and recent reports indicate that his feelings have not changed as he refused to shake hands with David Bernstein, the FA chairman (via the Guardian).
Would the Chelsea defender now feel any less antagonistic toward the organisation? And should he? It was the FA who stripped him of the England captaincy and pressed ahead with charging him after he was cleared by a court of law. If Tery couldn't commit 100 percent to the team cause while representing the English FA, it would no doubt be better for all parties if there was no return anyway.
