Transfer window is still open.

First, I think we know exactly what Liverpool is for the most part. We should expect an open game against City with goals going both ways. The outcome won't tell us too much - barring a lopsided victory. What is more telling is whether Klopp can solve the puzzle of bottom table clubs parking the bus. Fortunately, I don't see that as a problem in Champions League.

As for Mignolet, I think that it's pretty clear that Klopp has a (good) dilemma in that he has three goalies that are all fairly decent, but nothing to write home about. Ward may end up being the best, but he's still young. Karius hadn't played a league game since being dropped last December. I'm guessing that Klopp was trying to make sure that he had a reliable #2 (and someone to push Mignolet) so that he could feel comfortable sending Ward out on loan. Of course Arsenal didn't show him a damn thing!
