Bolton once again proved the class with a great win over newly promoted West Brom. The Baggies created the better chances with Peter Odemwingie spurning three excellent openings for the visitors.
But West Brom fell behind before the break when Lee Chung-Yong showed great composure to tee up Matt Taylor who side-footed in from close range.
And Elmander sealed victory late on, slotting home at the second attempt. The Swede's ninth league goal of the season - with only four minutes left - came towards the end of the home side's best spell of an enthralling game.
Brom have been linked with bids for Daniel Sturridge and Martin Skrtel in the January transfer window.
