Haha, We will take him when he is winning and that is for sure. And as a Scottish Brit myself, Alistair aint no Dutch name. In fact, if he ever appears on the next British show in North England or here in Scotland, I might head along and get an "ALLY!" chant going. Although that might be risky in Glasgow. For obvious "football related sectarian shithole" reasons.
He was born in the UK (England, I think. To be specific.) and moved to The Netherlands as a child. I regard him as Dutch......but I will claim him as British when he is a winner. As any nation that wants success SHOULD.
Ally is my new nickname for Overbrit.
