Argentina had to chase their Group A opener from the 47th minute when an error by midfielder Ever Banega allowed Bolivia to sneak into a shock lead against the hosts before substitute Sergio Aguero equalised half an hour later.

"They surprised us with a crap goal and we managed to draw  thanks to Kun (Aguero), but we're sad because we didn't reach  our objective. We did some things well but we have to keep  improving," Messi told reporters.

Bolivia's point in the match in La Plata was the first they  have ever picked up in a competitive match on Argentine soil.

It also denied Argentina revenge for a 6-1 roasting under  former coach Diego Maradona in a World Cup qualifier at high altitude in La Paz two years ago.

"A night without altitude" was the headline in the daily Clarin in a play on words on the expression in Spanish which would better translate as a night without class.

Argentina played into the hands of a modest but well organised Bolivia, failing to execute coach Sergio Batista's passing game modelled on Lionel Messi's club side Barcelona.

"It's very difficult to play like Barcelona, but the idea is ball possession," Batista told reporters.

"We tried to play and be a team with a lot of the ball, but Bolivia put a lot of people in the middle and clogged the spaces. It was a difficult debut."

TEVEZ FAILURE

Batista said on the eve of the match he had not recalled forward Carlos Tevez just because of popular demand.

He explained that with the "player of the people" in his side he would get more football and less "vertigo", meaning less headless running at the opposition defence.

Yet Tevez and Ezequiel Lavezzi, the two players flanking Messi in attack, did just that with the former earning some of the lowest match ratings in Saturday's papers.

Messi received an ovation from the crowd, but not for the reasons he would have liked, when he stood up to Bolivia's captain Ronald Raldes after a clash in the box.

Most Argentina fans regard Messi almost like a foreigner, with the forward having never played in the domestic league following his departure to Barcelona barely into his teens.

Attitude is what the home fans are looking for from the diminutive 24-year-old, who in the past has been criticised for a perceived lack of passion in an Argentina shirt.

The world's top player desperately wants to win them over like he has the Barcelona fans with his scoring exploits in Spain and Europe with 180 goals in 269 matches.

But Messi, despite some brilliant goals in friendlies, has gone a remarkable 13 competitive internationals without scoring since a 4-0 home win over Venezuela in a World Cup qualifier in March 2009.
