Brentford midfielder Nico Yennaris paid Cardiff the ultimate compliment by saying they are horrible to play against.
Neil Warnock's Bluebirds will certainly provide the Bees, who go into the game on a nine match unbeaten run, a stern test.
And Yennaris knows that he faces a hard-fought 90 minutes in Wales but is confident of picking up a result, provided the Bees stick to their game plan.
He said: “They're horrible to play against. The normally go man for man. It's always going to be a tough game.
“They're normally six foot, big, strong and physical. It'll be a good test for us on the weekend as we've been hitting form of late."
He added: “We have our game plan and what we stick to and how we play.
“As long as we approach the game in the right frame of mind, our football can do the talking, rather than what they're doing. As long as we stick to our game plan we'll be all right.”
Yennaris sees Cardiff's wide players as one of their major threats but also hailed Brentford's full back options going into the tie.
He explained: “They've got two good wingers in Hoilett and Mendez-Laing. They're pacey guys and have trickery to them. We know they can cause a threat.
“They're their more creative players but we've got two top full backs and we've seen top teams. It's not all about physicality. The ball does the talking.”
