Speaking after River Plate's 2-0 loss to Universidad San Martin in their opening Copa Libertadores group match, coach Diego Simeone stated that he felt his team made it too easy for their opponents by making errors at vital points in the match.

Simeone did not speak to his players or his coaching staff for some time after the game had ended as he needed to gather his thoughts after an embarrassing defeat against the Peruvian side.

He spoke to the press fifteen minutes after the final whistle, but was in a visibly blunt mood as he explained the result.

"Each game of full of details and they knew to take advantage of them and for that reason they won. The team that commits errors, loses; we committed errors," he told reporters.

Simeone indicated that this result does not threaten their chances of qualification from the group as "we are still at the beginning", but does feel that it is now imperative that they "add points" in their next game against Club América of Mexico on the 27th February.

When asked if he was worried by the performance, Simeone would not get any specific details, stating that "I will speak to the players about that," but did concede that they "must improve".

Simeone felt that Roberto Ovelar opener in the 15th minute made their game-plan difficult, stating that "the first goal arrived earlier than he had hoped or imagined it would", although he felt that "the team improved as the game went on" and believes that "although the team didn't play a good match, we could have drawn".

He stated that he was not surprised by San Martin's performance as "they have interesting players... Leguizamón and Del Solar have great technique".

Simeone concluded the short interview with a summary of his team's performance.

"We played ok, but not as we wished to before the game. Obviously, when you don't play well you don't get the result."
