In the Copa Argentina has been a shadow of their selves in almost every match they've played, but Argentina's win over Colombia is what Messi has tagged their best ever performance.
The match ended goalless after extra time and Argentina won 5-4 on penalties. The Albiceleste was in charge for the whole match, unlike their previous matches, where they lose control in the second half.
Argentina captain Messi has called the win Argentina's best performance at the copa.
"We played our best match of the Copa America," Messi told TVP.
"We create a lot of chances… Unfortunately we were able to get a goal and we were eventually lucky to win on penalties."
Carlos Tevez hit the winning kick to book a place in the last four, where they will come up against either Brazil or Paraguay.
Messi, who was named man of the match, has hit just one goal in the tournament, scoring from the penalty spot in Argentina's opening match against Paraguay which ended in a 2-2 draw.
