Rosenborg captain Mikael Dorsin is demanding a response in Europe after his team's Norwegian title hopes all but evaporated last weekend.
The Trondheim club had been locked in a three-way battle for their domestic crown with Molde and Stromsgodset, but have now lost to both their rivals in successive weeks.
Sunday's 2-1 defeat by Stromsgodset has left them four points off the pace with just two matches remaining.
Dorsin has said he is not ready to settle for third place just yet, but is anxious to make sure the Europa League campaign stays alive.
After losing to Metalist Kharkiv at home last month, the Norwegians now face the Ukrainians again knowing that defeat could knock them out of that competition.
Defender Dorsin said: ``To take the next step we need to move to a higher level and be more consistent. There are too many deep valleys. We need to be clearer and place higher demands on each other.''
Coach Jan Jonsson, who has faced criticism over his side's apparent capitulation, is also not ready to concede defeat yet.
He said: ``No, that's right. We will never be completely satisfied, and it's something I can attest to. We still have two games left so we will evaluate at the end of the season.''
Rosenborg's season started to go wrong in their last encounter with Metalist, which preceded the two vital league games.
Jonsson's side led with 10 minutes remaining after Tarik Elyounoussi's opener but late goals from Marlos and Cleiton Xavier condemned them to defeat.
Another win for Metalist, who share the lead of the group on seven points with Bayer Leverkusen, would secure their place in the knockout stages.
The ambitious Ukrainians reached the quarter-finals last season and have their sights set on qualifying for the Champions League next year.
