Argentina boss Gerardo Martino believes Lionel Messi played his best games for his country during this summer's Copa America.
Messi was slammed by critics and some supporters following the Albiceleste's final defeat on penalties to host nation Chile, with the Barcelona star having scored just once during the competition.
However, the 28-year-old was named in the team of the tournament and was reported to have turned down the prize for best player, with Martino adamant his performances were of a high caliber.
