Munich - Arturo Vidal's early header was enough for Bayern Munich to beat Benfica 1-0 at home on Tuesday for a slender advantage from the first leg of their Champions League quarter-final.
The Chilean midfielder struck in the second minute, heading home from five meters (yards) after being picked out by Juan Bernat.
Vidal had most of the chances for the rest of the game, with Benfica's defenders doing well to stifle Robert Lewandowski and Thomas Mueller, the home side's top-scoring forwards.
Lewandowski missed the best opportunity to wrap it up in the final minutes, when he sent a wayward pass for Philipp Lahm with an open goal beckoning.
Bayern is bidding to reach its fifth consecutive semi-final, while the Portuguese league leader is hoping to reach its first since 1990.
