Carlos Tevez and his former Manchester United team-mate Gabriel Heinze were both in the doghouse yesterday after a comedy of errors in the first half of Argentina's 1-1 draw at home to Paraguay.

Tevez, sent off in the first half for the second time in three internationals, is automatically suspended for tomorrow's visit to Peru after being booked and then receiving a straight red card for a studs-up challenge on Dario Veron.

He could find himself out of the team for longer after Sergio Aguero, his direct rival for a place in the attack, came off the bench to score Argentina's equaliser in the World Cup qualifier.

Heinze, who has never been a unanimous choice to play on the left side of the defence, was taken off at half-time after scoring an own goal in the 13th minute and injuring goalkeeper Roberto Abbondanzieri in the process.

"It was my mistake and I admit it, I take all the responsibility," Heinze told Argentine media after he misjudged a long ball into his penalty area and headed it past Abbondanzieri.

His future, however, looks brighter than that of Tevez, who had only just been given another chance by coach Alfio Basile after being sent off for petulantly kicking an opponent in the 2-1 defeat by Colombia in November.

Tevez has yet to score in the qualifiers while Atletico Madrid's Aguero, who helped the under-23 team win the gold medal at the Olympic Games in Beijing last month, has already notched two.
