Anderson Talisca scored the only goal of the game as Benfica secured a vital Champions League victory against Monaco in Lisbon this evening.

The hosts were first to threaten, firing a warning shot in the opening stages when Eduardo Salvio went on a mazy run and let fly, forcing visiting keeper Danijel Subasic into a comfortable save.

Salvio caused Monaco more problems in the 12th minute, whipping in a cross from the right that eventually found its way to Nicolas Gaitan, who fired wide.

It was Gaitan who was at fault when Benfica almost fell behind in the 23rd minute, the Argentine giving the ball away cheaply to allow Monaco to stage a quick counter-attack.

Monaco had defender Andrea Raggi to thank for preventing them from falling behind moments before half time, the Italian producing a last-ditch block to stop Gaitan from finding the back of the net.

Yannick Ferreira Carrasco caused Benfica all kinds of problems in the second period, and he was unlucky not to open the scoring on the hour mark, Cesar producing a good stop to steal the ball from his feet in a one-on-one situation.

End-to-end action ensued, but Benfica snatched it with eight minutes remaining when slack marking from Monaco allowed Talisca to smash home at the back post following a set piece.

Benfica remain bottom of Group C despite the win, but are now just one point behind Monaco in second with two games to play.
