Ray Stewart, great penalty taker, he just seemed to 'twat it' and it was in the net.
Like most fans, I kind of expect my team to miss and the other seem to score them. Sergio was a phenomenal goalscorer, but he missed a few over the years.
As others have said ,Ya Ya and Mario always inspired confidence (Balotelli seemed too confident sometimes) Going back, always had confidence in Dennis Tueart, though I think he missed two pens in one game once
Can't remember any other City player doing that (I'm sure someone probably has?!)
