Edgardo Bauza leapt to the defence of his Argentina players after they beat Colombia 3-0 to end a four-match winless streak and put their 2018 World Cup qualifying campaign back on track.
A 3-0 thrashing at the hands of rivals Brazil last week left Argentina sixth in the South American qualifying table, with only the top four guaranteed a place in Russia.
But Lionel Messi put in a star turn, scoring a stunning free kick and creating the other two goals, as La Albiceleste leapfrogged their opponents with a commanding display in San Juan.
"I never felt that the players had any problems,'' said Bauza. "They were always very close to me.
"These players always want to win and are the first to get to work. These players live their lives for this shirt and they will keep doing it''.
Nicolas Otamendi headed a Messi free kick over the bar early on, but the Barcelona forward soon took matters into his own hands as he curled in a 25-yard effort on 10 minutes which clipped the bar on its way in.
Radamel Falcao headed over James Rodriguez's free kick and Argentina capitalised on that let-off as Lucas Pratto headed home Messi's cross from the right in the 23rd minute.
Angel Di Maria hit the post in the second half but eventually got his name on the score sheet after 84 minutes, with Messi again the provider as he cut the ball back for the Paris Saint-Germain forward to fire into the roof of the net.
"It was not an easy match,'' added Bauza. "I'm happy because the players deserved this victory.''
Colombia coach Jose Pekerman felt Messi was the difference between the two sides.
"I'm very sorry for the way they gave away the first two goals,'' he said. "Messi in this form is impossible, because he makes a remarkable difference.
"We started the match well and if we had converted from time to time then it could have been a different story, but they scored fast and it was already difficult.'
"We lacked experience, we made mistakes and we paid dearly.''
