Chelsea boss Thomas Tuchel is adamant their 5-2 thrashing by West Brom was a blip.
The Blues' shock loss at Stamford Bridge saw their 14-match unbeaten start under their new manager come to an extraordinary halt in the Premier League clash.
"We can be very hard and very critical if not happy with a performance, we can point out things we like and don't like even if we win," he said.
"We won in many areas, passing, possession, the statistics, even in expected goals. If we play the same game again I would bet a lot of money that we win 99 times out of 100.
"We neglected some principles of our defending and we got punished. We talked about it for sure, it was about our body position and being sloppy in the build up. It costs us yellow and red cards."
