SERGIO AGUERO missed the chance to double Manchester City's lead at home to Chelsea on Sunday with what was quickly dubbed the 'worst Panenka' penalty ever.
The Argentine club legend, 32, is set to be released at the end of this season.
City are on the brink of reclaiming the Premier League title from Liverpool and have also finally made it to the Champions League final - where they will face Chelsea.
But Aguero endured a nightmare passage of play in the dress rehearsal league clash with the Blues.
Shortly before half-time, Aguero mis-controlled Gabriel Jesus' cross with an open goal at his mercy.
Raheem Sterling charged in to smash the ball home, almost off the toe of stumbling Sergio.
But Aguero had the chance to redeem himself just moments later after Billy Gilmour was adjudged to have bundled Jesus over in the box.
The Argentine confidently grabbed the ball as he looked to double his side's lead in the third minute of just one to be added on to the first period.
Aguero bravely attempted the Panenka, but was left immediately regretting his choice.
The Etihad icon's effort was so time, Chelsea stopper Edouard Mendy didn't even have to move as he gratefully accepted the ball into his chest.

Commentators around the world were left flabbergasted, with one French pundit quick to call it the 'worst Panenka ever'.
Speaking on Sky Sports, pundit Jamie Redknapp called it a 'Pa-stinker' while Micah Richards revealed he was left 'cringing' watching it.
Redknapp added Aguero looked like the 'naughty boy at school' after glancing over at a baffled Pep Guardiola.
To make matters worse, had Aguero scored he would have drawn level with Manchester United legend Wayne Rooney for most Premier League goals with a single club on 183.
It was Aguero's first penalty miss at the Etihad since Maarten Stekelenburg prevented his effort against Everton in April 2016.
The Argentine joins Kevin De Bruyne, Ilkay Gundogan and Sterling in missing Premier League penalties for City this season alone.
