So you expect robots? Players make errors, it's about minimising risk. Three errors in 10seconds is what raked in Chelsea's goal, not one individual error.
Yes, 3 individual errors.
Players aren't robots and expected to make errors every now and again but we make so many. I believe we have made the most defensive errors in the league for the past 2-3 years according to Opta.
We have conceded around 50 goals per season for the past 3 seasons - are you saying that it's ok because players aren't robots and errors are to be expected? I'm sorry but that's unacceptable.
