They have a very good midfield in Goretzka,Thiago,Martinez and Rodriguez, any of them can play in there and do a very good job.
Their weakness is their center-halves and dealing with pace. Won't be an easy game by any means, but if Kovac is still there imo that's a plus in comparison to Klopp.
Some of their lot are confident since we lost away from home, they think we got lucky. Prepared to be surprised.
