The Bees head coach addressed questions about the play-off chasing Whites and was full of praise for Slavisa Jokanovic and his team.
He said: “We know what a good team they are. They deservedly beat us at home and they're pushing for the play-offs and a win guarantees them that. If results go their way they'll make it and they'll be a threat in the play-offs as well.”
Smith also gave the latest news from the Brentford treatment room, outlining that he has the same squad to choose from from last week's 3-1 win over west London neighbours.
With the Bees secure in the Championship, there could be a case for rotating but with it being a west London derby Smith will be doing no such thing.
He added: “I said a few weeks ago I didn't feel I was weakening the team by putting Jack in against Barnsley but I'm sure the supporters want to see the strongest team.”
