Liverpool ease into Champions League quarter-finals after tame scoreless draw

Liverpool eased into the quarter-finals of the Champions League for the first time in nine years with no great alarm in a lifeless goalless draw at home to Porto.
This game was the antithesis of their 5-0 win in the first leg at the Estadio do Dragao, but a professional performance, a fifth clean sheet in eight European matches and no apparent injuries represented mission accomplished.
