Arsenal eased into the fifth round of the FA Cup with a win over Wolves.
Patrick Vieira put the Gunners ahead when he scored from the spot after Thierry Henry was brought down by Wolves keeper Michael Oakes.
A Freddie Ljungberg shot from close range confirmed Arsenal's dominance despite Oakes pulling off vital saves to keep his side in the match.
Henry had earlier had an effort ruled out after stealing the ball off Oakes and scoring.
Wolves manager Glenn Hoddle had plenty of incentive in trying to beat the Gunners having been a player and manager for their arch rivals Tottenham.
But, although his Championship side did not look overawed, they were outclassed in a game which started in lively fashion when Arsenal failed to capitalise on the chances they created.
Henry won the penalty when brought down by Wolves keeper Oakes
Henry broke clear of the Wolves defence and raced through on goal but decided to blindly cross when it seemed the better option was to shoot.
The trickery of Arsenal's Emmanuel Eboue was causing Wolves concern and he had a penalty appeal turned down after seeming to go down over Joleon Lescott's stray leg.
Robin van Persie had a shot well saved by Oakes who also saved at the feet of Jose Antonio Reyes as Arsenal exerted more and more pressure on the visitors' goal.
Eboue then hit the crossbar before the Highbury side thought they had gone ahead when Henry stole the ball from Oakes as he threw the ball up and attempted a goal kick.
The Arsenal striker walked the ball into the net but referee Mike Riley disallowed the effort.
Wolves seemed to grow in confidence after the break with the scores on level terms but that was shattered when Vieira stroked home from the spot to put the home side ahead.
Oakes could not save the penalty but kept Wolves in the match with saves from a Van Persie volley and Henry close range shot.
But he could not keep out a Ljungberg shot at the far post which put Arsenal out of Wolves' reach and gave a more realistic reflection of the match as a whole.
Arsenal manager Arsene Wenger:
"The Wolves centre-backs had an outstanding day.
"And, if we wanted an intense physical preparation for Tuesday (when we play Manchester United) then it was a good one.
"I smelled that it would be a difficult game although I was a bit surprised by their commitment and organisation."
Wolves manager Glenn Hoddle:
"He's a Premiership referee and there was definitely a familiarity between him and their players.
"I don't know how they choose the referees but it has got to be looked at.
"We had a cast-iron penalty not given to us and they got a penalty which was soft; some referees would give it, some wouldn't."
