We need to be the same in terms of attitude and competitiveness in this game.Garry Monk.
Che Adams scored a first-half brace as Blues secured their first win of the Championship campaign back in September, with Leeds suffering their first league defeat.
And it was not until five minutes before the end of normal time that Leeds fashioned their first meaningful attempt on goal, from which Ezgjan Alioski subsequently scored.
"You always have to be good defensively against any team, but especially against a team of the quality of Leeds," said the Blues boss.
"But we proved that in the first game where they didn't have a meaningful shot on goal until the 85th minute, when they actually scored their goal.
"That just shows how well we did defensively against them and how disciplined and focused we were.
"We need to be the same in terms of attitude and competitiveness in this game."
Blues head into the Leeds fixture on the back of a five-game run of defeats.
In the last two games in particular they created enough openings to have picked up a minimum of a point, although they were let down by one or two costly defensive lapses.
"We're not a team that can be anything other than 100 per cent," continued Monk. "We don't have that luxury.
"But of course, we've been working on certain tweaks about what we need to do in this game that could be different from before and try and execute those plans.
"But the main bulk of it is being able to deliver your performance defensively when you are playing against better squads. You have to be right on your game."
