Friday did not go according to plan for Uruguay. La Celeste were beaten 1-0 by Lionel Messi's Argentina in their Copa America opener.

It was another match and another blank for Uruguay, who have not scored this calendar year amid a four-game winless streak.

Not since 2013 have Uruguay got the better of their old rivals, while Argentina are undefeated in five games against Uruguay at the Copa America.

Despite Uruguay's current problems and attacking woes, even with Luis Suarez and Edinson Cavani in the line-up, Oscar Tabarez's legend continues to grow.

Tabarez is battling an ailment but is still serving the football-mad nation, dating back to 2006.

His story is not only legendary, but inspirational.

Tabarez has Guillain-Barre syndrome – a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system.

But that has not stopped the 74-year-old in his second stint in charge of Uruguay, having also coached La Celeste from 1988 to 1990.

Responsible for resurrecting Uruguay, Tabarez still celebrates goals even as an elderly man with a stick, struggling to walk.

"I am not living with any pain. This neuropathy sometimes causes me problems, especially to walk. But since this is a chronic illness, sometimes I am a little better," Tabarez previously said, having been expected to resign in 2016 following the diagnosis.

Tabarez, remarkably, is overseeing his seventh Copa America campaign. He guided Uruguay to their 15th CONMEBOL crown in 2011 and first since 1995.

Only three other coaches have managed more Copa America matches than Tabarez – a primary school teacher before embarking on a coaching career that has taken him to the likes of Boca Juniors and Milan.

On his watch, Uruguay have reached the quarter-finals on three occasions, finishing fourth in 2007. Tabarez's team also rode a wave en route to the 2010 World Cup semi-finals. A last-16 berth and quarter-final appearance followed in 2014 and 2018.

"What the Teacher achieved in this time is very big because he started totally from scratch," Uruguay goalkeeper Fernando Muslera said previously. "He has created everything we achieved and what is yet to come. If Uruguay is this respected worldwide it is because he made it."

Fast forward to 2021. His 31st meeting with La Albiceleste was a fruitless one for Tabarez and Uruguay, who have not conquered Argentina in Copa competition since 1989.

Uruguay have their work cut out this year but Tabarez has built a team that can never be underestimated.

More importantly, while silverware is at the forefront of El Maestro's mind, this is a story about human endeavour and a hero with an unwavering belief and refusal to quit.
