Chelsea last year at their place, the Morata goal. Smalling forced to go to Bakayoko, Valencia doesn't react and cover, a 2 week ongoing debate ensued, with the Smalling critics adamant that he had made the wrong choice. Of course if had stayed with Morata and Bakayoko smashed it in at the near post the debate would have been about that being the wrong choice.
Ekeke is not wrong, take Smalling out of it, his overall point seems to be on how we will forensically analyze goals we concede looking for blame but rarely give the same scrutiny to our hyped targets. Defenders, even the very best make a lot of minor mistakes in every game, a well organized unit is about being able to react and play scrambling defense so those little errors don't become a real issue.
