Horacio Carbonari. Not even kidding. He scored a screamer once, so we all used to shout "Carbonariiiiiiii" if the ball came to us about 25 yards out.
Or Shay Given if I was in goal, which I was quite a lot. I used to say to myelf "Save, Shay" if I stopped one going in the corner. This lass who played semi-pro nearly broke my nose by drilling one straight at my face and that was the last time I ever pretended to be Shay Given.
