I think the substiution of El Zhar on the right was significant. For 70 minutes their fullback played it narrow and showed kyut the outside which having no pace he never took so we played infield into a crowded part of the pitch. El Zhar came on and ran past him a couple of times on the outside, next thing you know there is a big gap between fullback and centre half which carragher stepped into and had a pot shot that flew in. no denying that the deflection was down to a huge slice of luck, but the shift in tactics which created the space wasn't lucky.
