Warburton admits that Leeds have shown their ability to play in a number of different formations, but he feels that Darko Milanic will line-up in a 4-4-2.
Milanic will take charge for the first time at Griffin Park and Warburton thinks that the Bees may have take on a cautious side, as a result.
“We are very conscious of the impact a new manager has and we need to snuff that out. Leeds will turn up on Saturday and we will have to be at it ourselves,” Warburton said to London 24.
“They’ve had a good run of results, but with a new manager coming in we’re not sure what impact his arrival will have."
“Leeds have played 4-4-2 in one game, a diamond and then 4-3-3 in another, but their manager tends to favour 4-4-2 in a quite conservative fashion.”
Leeds travel to London buoyed by the good form that the club have been on and Milanic will simply be hoping to continue with this momentum.
Neil Redfearn, who has been in caretaker charge for the last four matches, has guided the side to three victories and there is great positivity about Elland Road at the moment.
The Whites have climbed the table rapidly, but they face a tough test when they take on Brentford.
Although the Bees are still adapting to life at Championship level following promotion last year, they have been hugely impressive so far and a cautious approach may be recommended.
Brentford have a number of quick players, such as Alex Pritchard and Moses Odubajo, who can hurt defences if given too much space and Leeds will need to be wary of that threat.
That said, Milanic will be keen not to limit his own side's strengths and with their players full of confidence they will be determined to get the three points to give their new manager the perfect start on Saturday.
