They beat Stoke City 3-1 at home with Lyle Taylor and Chuks Aneke scoring either side of Tom Ince’s goal before Conor Gallagher sealed the three points with a late third.
Elsewhere, Preston put last week’s defeat against Millwall behind them with a 3-0 thrashing of Wigan at home.
They scored early and never looked back with Sean Maguire netting after just six minutes.
Louis Moult made it 2-0 seven minutes before half-time before a third was added by Paul Gallagher in the 53rd minute.
Sheffield Wednesday are the only other team who have a 100 per cent record in the Championship as they beat Barnsley 2-0.
