The 32-year-old was banned for three months by CONMEBOL after criticising the South American governing body during this summer’s Copa America, both after a semi-final loss to Brazil and a third-place play-off win over Chile in which he was sent off following an altercation with Gary Medel.
Messi however made a triumphant return as he scored the only goal of the game in Saudi Arabia.
“At the beginning we tried to play, we made a few mistakes and they created some chances,” Messi told the Argentinean FA’s official website.
“In the second half we improved a lot.
“I think this system defensively gives us a lot. It’s good that we can play in several ways.
“When you win, you work with peace of mind, it is very positive for what is coming.
“We all ran a lot – it’s what we had to do.”
