Owen Coyle was celebrating his biggest win as Bolton manager and one that eases their relegation worries after a comfortable 4-0 victory over Wigan.

Johan Elmander made the breakthrough at the Reebok Stadium in the 10th minute but it was only in the second half they took full control.

Kevin Davies extended their lead from the penalty spot before Fabrice Muamba scored his first goal for the club with substitute Matt Taylor also on target.

Bolton scored in the 10th minute after Davies managed to get the better of Titus Bramble. The ball broke to Elmander and the Sweden striker shrugged off Gary Caldwell to send a shot beyond Chris Kirkland for his third league goal of the campaign.

Wigan responded in the 19th minute and Paul Scharner got clear of his marker when Victor Moses floated in a free-kick. Scharner was unable to get enough power on his header and Jussi Jaaskelainen saved.

There was a scare for Wigan in the 26th minute when Lee Chung-yong delivered a corner from the left. The ball broke to Andy O'Brien but his effort was diverted to safety.

Wigan launched a swift counter attack in the 36th minute and Charles N'Zogbia showed good pace to create an opening for himself, but his effort from the edge of the area failed to trouble Jaaskelainen.

Bolton extended their lead three minutes into the second half after Tamir Cohen was bundled over by Caldwell. Davies drilled his spot-kick into the corner for his seventh goal of the campaign.

Bolton made it 3-0 in the 53rd minute following some good skill from Muamba. The 21-year-old midfielder turned Caldwell inside out before firing a shot beyond Kirkland.

Bolton went further clear in the 69th minute when Caldwell failed to deal with Elmander's back header and Taylor scored.
