Kilmarnock manager Kenny Shiels has warned his players against taking their foot off the gas following their shock win over Rangers at the weekend.
Killie ended a 17-year wait for a victory over Rangers at Rugby Park when Manuel Pascali grabbed the only goal of the game against the Clydesdale Bank Premier League leaders on Sunday.
Next up is the visit of second-bottom Aberdeen and Shiels has challenged his side to prove they can also deliver against teams at the other end of the table, saying: "We've been hammering that home, that we must produce and keep on producing."
He added: "It will be a tough encounter. Aberdeen did well last week to come from behind and showed good character. They've got good players so we will need to be at our best to beat them."
Shiels admits he is unsure what to expect against the Dons on Saturday because most teams - other than pacesetters Rangers, Celtic and Motherwell - have been so unpredictable this season.
He added: "We are all Jekyll and Hyde because it is so even. There are not many teams who have won many games. There are going to be fluctuating performances from all the teams outside the top three. It makes it very interesting.
"You can't say that we're favourites to beat Aberdeen or Aberdeen are favourites to beat us. It's one of those games where you expect the unexpected."
Kilmarnock will be without Danny Buijs - who is out for up to six weeks with a hamstring injury - and Liam Kelly who has a virus.
Buijs has already been sidelined with a similar problem earlier in the campaign.
Shiels said: "It is disappointing. It's out of my hands and we can't do anything about it. We just soldier on and put out what we think is our best team and go from there."
