Wigan Athletic have dran 2-2 with Botev Plovdiv in Austria after taking the lead twice during the 90 minutes.
Wigan managed to get the breakthrough after 22 minutes through a David Jones free kick, which he received back to flick and volley the ball into the back of the net.
Plovdiv responded minutes later through Cvetkov, who drilled the ball to the edge of the box and took his shot, which fired home to draw level in the first half.
Roberto Martinez's men came out on the front foot for the second half and were rewarded with a goal on the 54th minute through Mauro Boselli, who headed the ball into the bottom corner.
Plovdiv got back into the game yet again after trailing 2-1 by equalising through a Cvetkov penalty, which was won after Dyakov was brought down by Golobart in the box.
