Everton midfielder Pienaar excited with long FA Cup run
The 30-year-old said: "We don't have to talk about it now. The most important thing is Wigan and it is not going to be an easy hurdle to go past.
"That is important and at the final whistle maybe we can talk about it."
Everton will at least go into the game in positive mood after the disappointment of last week's late capitulation at Norwich.
Pienaar said: "It does give us a lot of confidence but the FA Cup is going to be a totally different game.
"We all know it is not the same as the league. We are playing against good opposition, so it is going to be hard. With the 12th man behind us hopefully we can go all the way."
