The power of Anfield is a phrase I've heard used a lot in recent years, particularly after Liverpool have recorded a momentous win.
I know it's a term that winds up opposition fans, who dismiss it as spin. But I also know from experience there is some truth behind it, because the stadium is like no other in the country. It has the ability to get into your head.
The first time I played there, in November 2006, I remember looking up at The Kop and feeling as if my own power was being zapped.
