He was just making a joke, Gerd. It probably would have been funny for you too if you had seen the match.
The situation was a stonewall handball in the box by Cahill, almost stopping the shot like a goalkeeper.
In my subjective view, Chelsea didn't deserve the win - two very lucky goals and a clear pen not given against them - but neither did Liverpool, they created almost nothing in front of Courtois, Can was lucky with the deflection as well. A draw would have been a fair result IMO. But with Chelsea this season, one can always expect that they will scrape through with the points no matter what, so there's that. That's always the sign of the future champions...
