Dylan Aquino scored in the second half as Argentina's Lanus reached the Copa Sudamericana semifinals on Tuesday with a 1-1 draw at Fluminense.

Agustin Canobbio put the Brazilian side ahead in the 20th minute at the Maracana with a close-range finish after Luciano Acosta's headed pass.

But Aquino equalized on the night with a low strike following Marcelino Moreno's pass on the counterattack.

The result gave Lanus a 2-1 win on aggregate and set up a place in the last four against either Universidad de Chile or Alianza Lima.

"We know that the start of games are always tough at this stadium so our plan was to get through the opening minutes and then take advantage when their intensity dropped," Lanus manager Mauricio Pellegrino told reporters after the match.

"We played against a very high level opponent and this result gives us great confidence going forward," he added.

Lanus is aiming to win the Copa Sudamericana - South America's equivalent of the Europa League - for the second time, having also lifted the trophy in 2013.
