Chelsea supporters: you're fine to watch this one.
This isn't your Willian, who netted that brilliant goal against Norwich City at Carrow Road last weekend.
This is the Willian who is currently on loan from Metalist Kharkiv at Brazilian side Cruzeiro.
But on the evidence of this shocking miss, his loan spell is unlikely to be made permanent.
The 27-year-old had the goal at his mercy after São Paulo goalkeeper Dênis had parried the ball straight into his path inside the six-yard box, but instead of tapping the ball home, he ended up striking the near post.
Not only was it an embarrassing miss - but it also proved costly for Cruzeiro, who went on to lose the match 2-0 after conceding two goals in three second-half minutes.
