Mexican side Toluca claimed a surprise 2-1 win at Boca Juniors to top Group One of the Copa Libertadores after the first round of matches Wednesday.
Toluca came back from a goal down and a missed penalty to win the game and become the second Mexican team to beat Boca at La Bombonera after Cruz Azul won 1-0 in the 2001 finals.
"Playing here at La Bombonera is very tough as Boca have huge tradition in this tournament," Toluca playmaker Sinha told Fox Sports. "With dedication and effort you can build big teams. We know that winning away in the Copa Libertadores is very good."
A 22nd-minute penalty by Santiago Silva put six-time Libertadores champion Boca ahead and the game looked comfortable when Boca keeper Agustin Orion saved a Carlos Rodriguez penalty in the 51st minute.
Eight minutes later, though, Toluca equalized as Carlos Esquivel received a long pass and netted a right-foot strike.
And in the 72nd minute, Sinha assisted Edgar Benitez, who shot over Orion's body for the winner.
In the last minute of the game, Boca striker Lucas Viatri could have equalized, but his shot from outside the box hit the right post.
"We are angry because we wanted to win our first home game in the championship," Boca midfielder Cristian Erbes said. "We must think about the mistakes we made and correct them."
