Chelsea's 3-1 aggregate win, after a nerve-racking finale, means they will repeat their acrimonious semi-final of three seasons ago when the Catalans won on away goals.

Leading 1-0 from the first leg in Lisbon, Chelsea reached halftime in a dominant position after Frank Lampard scored a 21st-minute penalty and Benfica skipper Maxi Pereira was sent off for a second yellow card five minutes before the break.

However, twice European champions Benfica refused to lie down and grabbed a deserved equaliser with a Javi Garcia header with five minutes to go.

As the Portuguese pressed for a tie-winning goal, they were caught on the break as former Porto player Raul Meireles struck the winner in stoppage time to send Chelsea to the semi-finals for the sixth time in the last nine seasons.
