Aston Villa booked their place in the Uefa Cup group stages after a draw against Litex Lovech.
Marlon Harewood put the home side ahead on 27 minutes with a smart finish from 12 yards after a powerful run.
But Wilfried Niflore brought Lovech level when he converted a penalty on 52 minutes after Carlos Cuellar had been penalised for a foul on Wellington.
The equaliser had little effect as the Bulgarian visitors failed to trouble Villa's obdurate defence.
With the cushion of a 3-1 advantage from the first leg, manager Martin O'Neill opted to rest six of his starting XI from the 2-1 win over Sunderland, with one eye on the Premier League match against leaders Chelsea at Stamford Bridge on Sunday.
Gabriel Agbonlahor, Gareth Barry, Nigel Reo-Coker, Martin Laursen, John Carew and Curtis Davies were all rested, with record signing James Milner, Harewood, Zat Knight, Carlos Cuellar, Moustapha Salifou and Wayne Routledge earning starting places.
And it was the much-maligned Harewood who put Villa 1-0 up with a quality finish.
The striker received the ball 30 yards out from Ashley Young and took on the Bulgarian defenders before unleashing a powerful 12-yard strike past goalkeeper Todor Todorov.
Despite their three-goal aggregate deficit, Lovech continued to play neat, attractive football - but failed to create any significant goal-scoring chances.
Villa's Bulgaria international Stiliyan Petrov - handed the captain's armband in Laursen's absence - headed just over the bar from 12 yards with the last chance of the first half.
