In the Premier League, Crystal Palace midfielder Eberechi Eze continued his excellent debut season and added to the troubles of Wolves with the only Selhurst Park goal.
A bad game with a thumping finish, his third league goal since making the move up last summer, was fixed by the £ 19.5m signing from QPR.
In a game with little opportunities, Willian Jose was twice denied by Palace keeper Vicente Guaita in his first start for Wolves since joining Real Sociedad on loan.
Wilfried Zaha almost made it 2-0 on the counter-attack when he struck the crossbar.
The victory lifted Palace beyond Wolves, who fell to 14th in the table and in eight league matches are without a win.
This was a timely victory for Roy Hodgson’s side, who, after beating Sheffield United on 2 January, have taken one point from their previous three league games.
In that match, Eze also scored and the 22-year-old continues to be one of the major success stories of the Palace season.
Eze drilled past Rui Patricio after Jordan Ayew had rolled the ball into his direction to inject some much-needed life into a match that had become a terrible spectacle.
“I think he is a player who will improve all the team,” Hodgson said of Eze’s contribution.
“Most importantly of all he is getting used to the intensity of the Premier League and all the other things that the Premier League requires from you.
“After avenging their FA Cup loss by Wolves this month, Hodgson, who made six changes and leaving new signing Jean-Philippe Mateta on the bench, will hope his side will kick on.
In midweek, Wolves were planning to draw on a hard-earned point at Chelsea but ended up heading backwards at Selhurst Park instead.
Since losing talismanic center-forward Raul Jimenez to a severe head injury, they have taken just three points from the last 24 on offer and have won once in 11 league matches.
Brazilian forward Jose, who was brought in to fill the gap created by the absence of Jimenez, went close twice.
Guaita responded well shortly before Eze’s winner to tip a shot over the wall, and even held a header out in the closing stages.
Wolves are falling quickly without a goal in two games and this is definitely the toughest challenge of the reign of boss Nuno Espirito Santo.
Under the Portuguese, they have celebrated some memorable moments, but must start winning quickly to avoid being drawn into a relegation battle.
