Ruthless Leicester picked up their first away Premier league win of the season as they beat Wolves to move off the bottom of the table and out of the relegation zone.
Youri Tielemans put the Foxes ahead with a stunning 22-yard strike, which flew past Jose Sa and went in off the post.
Wolves had nine shots in the opening 17 minutes, but fell 2-0 behind when Harvey Barnes linked up with Kiernan Dewsbury-Hall and slotted past Sa.
Former Chelsea striker Diego Costa, still searching for his first goal since joining Wolves on a free transfer in September, had numerous chances but could not beat visiting keeper Danny Ward, who tipped one shot over and saved a header.
