They are - normally and throughout the whole season until some weeks ago. But their problems are cumulating in the last weeks, resulting in really bad games in the Bundesliga - like a really dull 0-0 at home against Hertha BSC last Saturday.
Their main problem ist that Sebastien Haller is injured - seemingly til the end of the season. He is the offensive brain, creating the assists, esp. by catching and securing long balls and relaying them to Jovic. With Rebic suspended in the first leg, Eintracht has a real problem, because Jovic, Rebic and Haller work really good only together (see this short analysis of Jovic and the role of the other guys on Youtube). That is the signature gameplay of Eintracht in this season. The only other real chance of getting the ball to Jovic are the full-backs Kostic and Da Costa going some extra miles on the left and the right - but they also really looked exhausted in the last matches.
So I am very excited to see what Adi Hütter is making out of this mess. It maybe won’t be the usual brilliant offensive play that we will see from Eintracht. But it should become an interesting match!
