Feeney sends Lions through

The 25-year-old's last-gasp effort proved the difference against the npower Championship promotion-chasers at St Mary's and sets up a home tie with Bolton.

Millwall broke the deadlock after 17 minutes when Liam Trotter struck home from close range but Adam Lallana pegged the visitors back with a superb solo goal and after the break substitute Rickie Lambert fired Southampton into the lead. Dany N'Guessan levelled with 11 minutes remaining before Feeney struck.

Millwall were the first team to enjoy a spell of dominance and it paid off in the 17th minute as Trotter fired home what looked to be a deflected effort from the edge of the box.

The south Londoners were looking dangerous and should have doubled their advantage shortly afterwards when Ryan Mason got behind the backline, only to curl a shot into the side netting.

N'Guessan fired into the side-netting as Millwall continued to press, before Lallana fashioned an equaliser in the 35th minute against the run of play. The 23-year-old showed individual skill that belied the home side's scrappy performance as he danced past the visitors' defence to fire past David Forde.

Steve De Ridder's right-wing cross was met by a Guly do Prado header that forced Forde into a sublime parried save that Lallana blasted over.

Saints continued to press in the second half as Lee fired just wide, before winning a free-kick wide on the left from which Lallana managed to strike the bar.

While Bartosz Bialkowski had to be on his toes to stop a Harry Kane effort at the other end, Saints were dominating and took the lead when Lambert fired home inside the box in the 77th minute.

Adkins' side looked all but set for progression before N'Guessan headed home a superb Henry cross two minutes later. Substitute Ben Reeves had a goal ruled out for offside as Saints pushed for a winner, which was secured by their opponents as Feeney struck home late on.
