With the Scottish Premier League title all but secured and a Scottish Cup semi-final against St Mirren or Hearts to come, Neil Lennon's side head into the League Cup final with a domestic clean sweep in their sights.
The Parkhead boss has tried to play down the hype surrounding his squad and their potential achievements this term, but they remain firm favourites to clinch a three-title haul come May.
Killie are the first side to be presented with the chance to halt the Hoops in their tracks, and Bell hopes Treble talk proves cheap as the Ayrshire men bid for a place in Hampden folklore.
He said: "We know Celtic will have their sights on the Treble.
"They need to get by us first and we will make it difficult for them.
"We need to perform on the day, everyone has to be at their best and then you never know what can happen.
"The talk is frustrating for us but we don't read too much into it. Celtic are in one cup final, it looks as though the league is over and they are in the semis of the Scottish Cup, so it is only natural people are going to talk about the Treble, but we will be going out on Sunday to stop that.
"Kilmarnock are due a cup win so we need to go out and perform. We know it is a massive task.
"We have not beaten Celtic in Glasgow for nearly 60 years, but anything is possible in football, especially in a cup game. We know we have got one game to go and perform so that is the challenge for us."
