To illustrate this is the kind of thing I detest in internationals and what I'd gravely like to avoid at any cost with ourselves.

Kevin Prince Boateng is essentially a german guy who wasn't good enough to play for Germany (he's brother is even a german international, and Kevin represented Germany at under 15, under 16, under 19 and under 21 levels.). When this was apparent and his stock from the hottest young talent in the Bundersliga declined to Spurs reserve and then a relegated Portsmoth has been he was surely about ready to give up on that and jumped at the chance of representing Ghana at the World Cup. A move purely engineered to get himself noticed on the biggest stage in that competition. It worked and he moved to AC Milan afterwards where he's reignited his career.
And now guess what happens? He's retiring from Ghana at the age of 24. ....24.
So yes I'm cynical because that kind of wavering loyalty from foreign based players sets a bad precedent, holds back players who'd love to play for their country and embarrasses the nation when stories like this emerge.
