Aberdeen manager Derek McInnes admits a Betfred Cup response is vital following their European disappointment.
McInnes believed Aberdeen could overturn a 2-0 first-leg defeat against Rijeka at Pittodrie on Thursday but the game unravelled after they lost an early goal and Funso Ojo to a red card on their way to another 2-0 loss.
Speaking ahead of Sunday’s trip to Tayside, McInnes said: “We need to analyse the performance and shoulder the responsibility.
“We need to make sure we are ready for Sunday, it’s a different challenge again but it’s a game that’s really important for us to give a response.
“I have watched Dundee a couple of times this season already, they have tried a few different systems and I think it will be a different system against us again.
“They have got plenty of experience in their team, a lot of new signings, they have a top-flight front two and players who we are well aware of.
“I am pretty sure they will be confident that they can get a result against us but we need to get the job done.”
