I think it's reasonable to expect that any football team should get around fifty percent of their attempts on goal on target. As you say though shit happens!
Agreed but our profligacy in front of goal is worrying. We haven't been consistent enough in front of goal for a couple of seasons now I'd say but unfortunately for us a clinical striker will cost us a fortune in this division.
With seventeen shots on goal at least half of them have to be on target and for me that is biggest damning stat of today. Charlton only had three on target and scored with all of them!
