The Welsh club go into the game with just one win in seven league games and pressure growing on the manager who led them to eighth place and their highest top-flight points tally last term.
Monk is convinced good results against Chelsea and Manchester United prove little has changed since last season's storming campaign, but says the time has come for his players to start producing on a weekly basis.
Monk said: "If you look at our performances against the bigger teams this season we have performed really well and played some of our best football but against teams around our level, we have not performed how we should.
"There's no excuse - it's about the players mentally preparing themselves to deliver the performances they have done in those (big) games.
"We have worked a lot on our mentality and our strength as a group, and we have to have the courage and the bravery to go out and play our way and impose ourselves.
"When we do that we are a handful for anyone and we are a very dangerous team, and it is about reminding the players of that."
Monk's men relieved some of the pressure with a priceless 2-1 win at Aston Villa a fortnight ago before last week's heavy defeat at home to Arsenal left them in 13th place in the table.
But Monk rejected suggestions that after a period of sustained success since arriving the top flight the club might be sliding towards a season of struggle at the wrong end of the table.
He added: "Every team has a difficult period in a season - last season we started really well but we also went through a period similar to this.
"In the last two games I have seen a lot more positive things and a lot of ourselves coming back
Of course results are the be-all and end-all, but if we continue to do what we're doing, I think you'll see the results come, for sure."
Monk once again has a fully-fit squad to choose from and indicated he will keep faith in striker Bafetimbi Gomis who has not scored since the win over Manchester United at the end of August.
Monk said: "I've got great confidence in Bafe
The whole team needs to work better to create chances for him
Bafe works well and is a good person, and the whole team is determined to work towards putting a string of results together."
