Robert Lewandowski scored twice as injury-hit Bayern Munich romped to a 3-0 league win over Eintracht Frankfurt on Saturday ahead of its Champions League quarterfinal at Porto.

Despite having only four fit players on the bench, Bayern dominated at Munich's Allianz Arena and is three wins from claiming a third straight German league title.

Lewandowski, the Bundesliga's top scorer last season, now has 16 goals for the season - good for third in the scoring race.
