Championship leaders West Bromwich Albion made light of atrocious conditions to breeze past Millwall with a 2-0 win at The Den to move four points clear at the top of the table.

On-loan Benfica midfielder Filip Krovinovic put the Baggies ahead in style before half-time while 20-year-old Dara O'Shea scored his first professional goal late on to seal victory for Slaven Bilic's side.

The Croatian manager was a relieved man as his team secured just a second win in nine league games to capitalise on Leeds United's defeat at Nottingham Forest on Saturday. Millwall had won their previous three league games at The Den - their best run in the Championship since 2011 - but their hopes of a playoff place were dealt a blow as they remain five points off the top six.

The visitors dominated early on and should have gone ahead when Matheus Pereira smashed a low effort off the foot of the post four minutes into his return from a three-game suspension. Despite the blustery conditions as storm Ciara took hold in London, the league leaders were constantly able to create chances.

Having been played through on goal by a pin-point Pereira pass, Hal Robson-Kanu failed to test Millwall goalkeeper Bartosz Bialkowski with a low shot.
