Aberdeen manager Craig Brown has warned his players not to get carried away with their cup win over Motherwell as they prepare to return to Fir Park.
The Dons stretched their unbeaten run to 13 games with a 2-1 William Hill Scottish Cup triumph in Lanarkshire last weekend.
However, that was their first win over Motherwell for three-and-a-half years and the home side are looking to keep the pressure on Rangers in the race for second place in the Clydesdale Bank Premier League.
Brown said on the club's official website: "I don't think last week's game will have any bearing on this week's game.
"They're totally different games, totally different tournaments and I am certain Motherwell will be looking to maintain their exceptional league record.
"We have to be totally focused, totally concentrated on the job and not for a second thinking that because we won last week that we just have to turn up to win this week."
Aberdeen are arguably favourites as Motherwell are struggling for available players at the back.
Centre-backs Shaun Hutchinson and Tim Clancy are suspended while Stephen Craigan is a doubt with an Achilles problem and Steven Saunders is still to return from his long-term injury.
Motherwell midfielder Keith Lasley is suspended after receiving a red card for the late tackle that put Dons midfielder Fraser Fyvie out of this week's game, although Brown will welcome Gavin Rae back from being cup-tied.
"They are not nearly as depleted as we are," the Aberdeen manager said.
"It is testament to the players that we got a victory because we were undoubtedly depleted last week and we will be depleted again this week."
Progression to the semi-finals of the cup, where they will face Hibernian, has given Aberdeen a huge lift after several indifferent years.
But Brown insists they must focus on the SPL as they look to mount a late bid for a top-six place.
"The priority is the league points," the former Motherwell manager said.
"We have a mathematical chance, a fairly solid mathematical chance of the top six.
"We have only got four games left and we are six points behind the team in sixth, Hearts.
"If they win two fixtures, even if we win them all, that would likely put them in the top six. We have to try and win all our games though and just see what happens."
