Leeds boss Marcelo Bielsa has warned struggling Birmingham will not be brushed aside at Elland Road today.
Championship pacesetters Leeds are the only unbeaten team after eight matches played.
Birmingham are yet to win this season but Bielsa has told his table-toppers - impressive 3-0 winners against Preston on Tuesday - not to be complacent.
"It is a long season and it is not a sprint," said Bielsa. "Birmingham concede very few goals, so that is a difficulty for us.''
Garry Monk, whose Birmingham side are 20th, returns to Leeds for the second time since he resigned last year to join Middlesbrough.
Monk is confident the Blues can get back to winning ways.
"We are defending very well and it's only individual mistakes that have hurt us.
"It's a results business: I'm here to win, the players are here to win. We're not going to let anything deter us."
Monk's former club Middlesbrough, one point behind Leeds, host Swansea, while third-placed Brentford go to Derby.
At the other end of the table, Millwall, five matches without a win, go to West Brom who are chasing a seventh straight home win.
Aston Villa keeper Andre Moreira could miss Sheffield Wednesday's visit with a knee issue. He's 50-50.
Ipswich boss Paul Hurst has urged his bottom-of-the-table side to be on the front foot against Bolton as they search for their first win.
"Being at home we want to take the game to them, and make it about us," Hurst said.
