Argentina's Arsenal and Chile's Union Espanola played out a goalless draw in the first leg of the Copa Libertadores round-of-16. This result means the tie is still open ahead of the second leg to be played on Wednesday in Santiago.

Arsenal defender Mariano Echeverria will miss the return match in Chile as he was sent-off in the 87th minute for elbowing Union attacker Patricio Vidal. Union went close to snatching the winner in the 84th minute but Arsenal keeper Cristian Campestrini saved Sebastian Jaime's header from Cristian Chavez's cross.

Arsenal's newly-appointed coach Martin Palermo was forced into making attacking changes after the visitors proved to be rock solid in defence, but despite this, his team failed to make the breakthrough. Jaime told Fox Sports this is a promising result for his side ahead of the quarter-finals. He said: "We leave Argentina with a good feeling.

"It was a quite hard match as we knew Arsenal were strong team at home, but the draw is positive for us. In the second half we managed the ball and have more opportunities. We hope we can define the tie at home next week."
