Former Leeds United boss Bielsa had found himself under pressure, with La Celeste going five matches without victory since finishing third at the Copa America.

However, it climbed to second in the CONMEBOL qualification group – ahead of Colombia on goal difference – by edging a five-goal thriller in Montevideo.

Andres Gomez's 96th-minute strike had appeared to salvage a point for Colombia, but Ugarte volleyed home after a knock-down from Facundo Pellistri mere moments after Uruguay had kicked off again.

Speaking after the dramatic finale, Bielsa said: "Victories like today are healing in the sense that they bring everyone closer, around a feeling as strong as Uruguay's connection with the national team.

"It was a very exciting match, and the players' determination to secure the win was evident.

"They have a well-oiled style of play; they defend, press, manage the ball, and have individual brilliance, which makes them a tough rival to beat.

"It's not easy to win against this opponent, as they have physically gifted, technically proficient players across all positions, many of whom can change the game's dynamics."

Next up, Uruguay faces Brazil, with the Selecao languishing in fourth after it played out a frustrating 1-1 draw with Venezuela last week.

Bielsa, however, is under no illusions regarding the magnitude of the task awaiting his team in Salvador.

"If Colombia is an athletically strong team with an offensively capable system that creates danger and has organisation in possession, Brazil has that and more," he said.

"We will try to control the ball in their half and not ours. Sometimes we succeed, and sometimes we don't, like against Venezuela."
