Championship side Wolves upset Premier League opponents Stoke City to reach the fourth round of the FA Cup, in front of 4600 euphoric travelling fans. Helder Costa''s low first-half shot and Matt Doherty''s stunning free-kick gave Wolves their first win in the competition for almost six years. Peter Crouch volleyed over from six yards and visiting goalkeeper Carl Ikeme made four excellent saves before Doherty''s set-piece sealed victory. Manager Mark Hughes had named a strong starting line-up, with Xherdan Shaqiri and Bojan Krkic among those brought into the side that beat Watford in the Premier League on Tuesday. But the Potters were below par for long periods and did not show their quality until the latter stages, as they were beaten by a team 25 positions below them in the league pyramid. Costa celebrated his goal in acrobatic fashion, he probably was unaware but it had been a long time coming for Wolves who had suffered two relegations, won one promotion and had seven different full-time managers since their previous win in an FA Cup tie - a 5-0 third-round replay win over Doncaster in January 2011. Two head coaches, Kenny Jackett and Walter Zenga, have departed during another eventful season at Molineux, but Wolves'' win at Stoke was more evidence of their ongoing recovery under boss Paul Lambert. A much-changed Wolves team caused their top-flight opponents problems from the outset in attack. Jon Dadi Bodvarsson had already sent two efforts wide before Costa, who is on a season-long loan from Benfica, found the net for the eighth time this season with a strike which beat Lee Grant at his near post. At the other end, a defence including fit-again Mike Williamson for the first time since November 2015 was rarely threatened by Stoke until the final 30 minutes, when Ikeme came to the fore. Named as captain with Danny Batth and Dave Edwards on the bench, Nigeria international Ikeme kept out efforts from Marko Arnautovic, Ibrahim Afellay, Crouch and Joe Allen to preserve his clean sheet. Unusually Stoke manager Mark Hughes did not blame the referee!
