And remembering the match day, the Norwegian official told Marca: "It was not my best day really. Some days you are not at the level you should be. I can't be proud of that performance.
There were several errors and everyone will have their opinion of those plays."
They were handball situations. I judge them on the pitch and I think it is interesting to know what I think of those actions once judged, although I understand that people think different to the decisions I made at the time."
After the final whistle, Chelsea players surrounded Ovrebo to argue for the referee's decisions. Didier Drogba and Jose Boswinga were banned by UEFA for their behaviour.
