Dortmund are starting off with a clean slate together with Niko Kovac... What do you say? Will his first times go nice in the Champions League and Bundesliga both? 
Their opponent in the Champions League playoffs is Sporting by the way. Since Amorim's departure I can't say they have got better here. But Gyökeres is still very dangerous as he is contributing to goals like a machine.
Dortmund on the other hand, they have been terrible with defending so far. Sacking Nuri Şahin was the right decision. But we don't have any idea about what Niko Kovac will do yet. I just hope to see some progress on their side. As a reminder, Dortmund were a finalist last season. I'm curious how far they will make it this time...
Mike Tullberg has given high standard to Niko Kovac because as interm coach Mike Tullberg have done well and his record is 2 wins and 1 draw from 3 latest matches i think Niko Kovac a bit under pressure because he must be able to do more than Mike Tullberg did and before this match Dortmund has a match against Stuttgart in Bundesliga so let see it later whether Niko Kovac can able to extended unbeated record from Dortmund or notTheir opponent in the Champions League playoffs is Sporting by the way. Since Amorim's departure I can't say they have got better here. But Gyökeres is still very dangerous as he is contributing to goals like a machine.

So basically the condition of both teams is not so different because they have a problem with the consistency which caused they have to changing the manager and Sporting have no good history in this competition because their highest achievement is only quarterfinal on season 1982-1983 and Dortmund as the finalist of last season probably as the favourite but it's hard to predict Dorrmund under Niko Kovac
