The 36-year-old produced another piece of brilliance, as his side booked their place in the MLS Leagues Cup quarter-finals.
Messi netted his team's first goal in the victory over FC Dallas, before then firing a trademark free-kick into the net late on, sending the tie to a penalty shootout, after the scores were tied at 4-4.
The sensational set-piece showcased Messi's brilliance, and capped-off his man of the match display.
Though had referee Cesar Arturo Ramos been more vigilant, it remains to be seen whether the goal would have actually stood.
An eagle-eyed fan captured Messi repositioning the ball on several occasions, before moving it to the left one step at a time, therefore increasing his chances of scoring.
