Carlos Tevez put Manchester City on the road to Wembley with an FA Cup hat-trick, two days after being arrested for a driving offence.
The Argentina striker also played a part in goals by Aleksandar Kolarov and David Silva as City crushed Barnsley 5-0 to reach the semifinals.
Tevez's goals came while out on bail after being arrested for driving with a suspended license.
"We know what he can do and he has shown what a great player (he is)," City defender Kolo Toure said.
Wigan will also be playing at Wembley next month after reaching the semifinals for the first time in its 81-year history by beating Everton 3-0.
But it was a bittersweet day for Wigan as the team was sucked back into the Premier League relegation zone after Aston Villa won 2-1 at Reading.
With a game in hand, Wigan is three points behind Villa, but a point above both Reading and bottom-place Queens Park Rangers, which beat Sunderland 3-1.
The tight relegation tussle is in contrast with the title race where Manchester United is 12 points ahead of City but in cup action when it hosts Chelsea in the quarterfinals.
The cup is City's last realistic chance of winning a title this season, and Roberto Mancini's side has reached the semifinals without conceding a goal.
Tevez took just 11 minutes to open the scoring against second-tier club Barnsley. After David Silva's strike was pushed onto the post by goalkeeper Luke Steele, Tevez was on hand to bundle in the rebound.
Tevez turned provider in the 27th, with Kolarov meeting his cutback to double City's lead. Tevez was on target again four minutes later from close range after connecting with Silva's pass.
And the hat trick was completed five minutes into the second half after being set up by Samir Nasri. Tevez was also involved in the buildup that saw Silva score after being denied initially by Steele.
"(The early goal) made a big difference because when you play against that kind of team you need to knock them down from the first minute, which we did and after that they lost confidence," Mancini said.
