Everton 4 Wigan 0
Marouane Fellaini's familiar bushy hair was back as he cut Wigan down to size with a fine personal display in Everton's biggest win of the season.

Gone was the braided hair-style for the Belgian midfielder as he turned on an outstanding performance, scoring one - his seventh for the club - and having a hand in the other three.
Wigan must have been relieved to see the back of him when he was taken off with 19 minutes to go, having never at any stage come to grips with Everton's lanky record signing.
His determined run set up Jo for the first, he scored the second himself and then saw two further shots palmed out by a shaky Chris Kirkland for Jo and Leon Osman to score from rebounds.
It was Everton's biggest win of the season and further cemented them in sixth place, while Wigan's European aspirations took a bad hit.
Everton had full-back Tony Hibbert back in the side after missing four matches with a thigh injury, which left Lars Jacobsen relegated to the substitutes' bench, along with Louis Saha who was replaced by Tim Cahill from the side that lost at Portsmouth last time out.
Cahill had a calf injury for that match, and had only just returned from playing for Australia in midweek, but boss David Moyes considered the club's top scorer was sufficiently recovered from the travelling to play.
Wigan, chasing seventh spot and probable European qualification, had Antonio Valencia back from injury, replacing Hugo Rodallega, but were comfortably swept aside by the Toffees.
Everton, in sixth and with an FA Cup semi-final later this month, still harbour hopes of Champions League, or at least catching Aston Villa in fifth.
And they got off to a bright start with Osman scooping one effort wide and then almost setting up Jo after a determined run into the box, before the Brazilian headed straight at Kirkland from a Hibbert cross from the right.
Wigan at least had one Egyptian on show, with the club now having received a fax from Amr Zaki's agent claiming his absence has been caused by a hamstring injury.
It is a situation that has hardly impressed Wigan boss Steve Bruce. However, Zaki's countryman Mido was left up front on his own.
And he forced a good save from Tim Howard from 20 yards after a clever backheel from Paul Scharner, sporting an interesting new red and blue haircut.
It did not prevent the Austrian getting in a good header from a Valencia cross.
But Everton continued their pressure and Kirkland produced a brave piece of goalkeeping to stop a Leighton Baines free-kick from reaching Jo and Osman.
But after 26 minutes Kirkland was well beaten by a Jo cross-shot into the far corner.
Emmerson Boyce looked to be holding Fellaini, but referee Phil Dowd allowed play to continue for Osman to find Jo in the box, with the Brazilian flashing his drive into the far corner.
Wigan picked up two quick bookings, Mario Melchiot for a foul on Steven Pienaar and Michael Brown for catching Cahill from behind in a combustible private war between the pair that had being going on since kick-off.
Wigan sent on an extra striker in Rodallega for midfielder Brown at the break, but any thought of a concerted fightback was shattered by three more Everton goals early in the second half.
The first came after 47 minutes when Hibbert crossed low from the right and Fellaini had too much time and space to hook his shot past Kirkland.
It got worse for Wigan after 51 minutes. Osman threaded a pass into the box, Fellaini's shot was palmed out by Kirkland for Jo to sidefoot home from six yards, his fifth for the club since joining on loan from Manchester City.
And on the hour, Kirkland was at fault again when he pushed out a 20-yarder from Fellaini for Osman to convert the fourth with ease.
Four minutes later Everton were able to give Cahill a rest, sending on teenager Jack Rodwell, fresh from his England Under-21 debut, while the Everton crowd jeered former Liverpool keeper Kirkland every time he touched the ball.
