My Opinion on this? he's not going anywhere.
On Loan? Perhaps but no way he's being sold. we have been following him since what 2012? for a possible successor for Valdes, and we finally bought him just a season ago and he played through out our CL and Copa Campaign and won the CL and Copa For us and he's only 23 years old.
Bravo despite being so good for us with him being 32 he isn't going to be around forever and it would be stupid if we sold Ter Stegen it would literally kill our Long term Future in the GK spot for Short Term success.
In my Opinion Like I said he should be loaned out with Intentions of him replacing an aging Bravo when that time comes, If Liverpool and Klopp are willing to do that that would be Great but if Not? Liverpool and Klopp should go away and find someone else then.
