Wayne Rooney is stepping into a wonderful footballing city and one where I crossed the divide, playing for Birmingham in the first half of 2006 and for Aston Villa in the second half.
As someone who experienced Celtic versus Rangers in Glasgow, I know a fierce rivalry when I see one and there is a distinct edge to the Second City Derby.
I scored my one and only goal for Birmingham — and my 150th in the English and Scottish leagues — in a showdown with Villa and the atmosphere was enough to induce goosebumps.
