The Bees, currently 11th in the Championship table, go into Saturday's game at Griffin Park against the high-flying Magpies on the back of a 3-0 defeat against Wolverhampton Wanderers.
“Notts County will be a potential banana skin for us,” Smith told the official Brentford site.
“They will be very tough. They have done fantastically this season. They have good, experienced players, we have to make sure there is no complacency and play to our strengths.
“We will patch the players up (following the busy festive period) as best we can for Saturday and we have others wanting minutes. We will go in to the game to try and win it.
"We will make some changes but that is more to do with players being spent after what they have put in over the past four games.”
