Whether it be bad refs, bad luck, near misses, importance of match etc. What loss annoyed or stung you the most in chelsea history? The one game that annoys me to this day is the champions league 2nd leg at stamford bridge against barcelona in 2009. We had a lot of shots on target with only one going in, barca had like two shots and one went in and barca go through on the ridiculous away goals rule. Obviously my main gripe was the worst reffing performance I had ever seen at our expense by that norweigen fellow who denied us 4 penalties and a chance to avenge the previous year's champions league final loss aginst man utd.
