West Bromwich Albion went top of the Championship table as they battered Sheffield United at The Hawthorns.
In a meeting of two of last season's relegated Premier League teams, Albion's physical dominance showed they have so far adjusted better to life back at this level under new boss Valerien Ismael.
Three of Albion's four goals came from aerial set pieces, triggered just as they were against Luton on Saturday by a headed opening own goal from a Darnell Furlong long throw.
After Jack Robinson headed past Michael Verrips, an error from the Dutch keeper - on his first league start - then led to an early second-half goal for Dara O'Shea before summer signing Alex Mowatt bagged a third six minutes later.
