He said that as a joke. Funny how raw text is so open to interpretation to some people... Eh...
He is saying so much because the press is asking him so much. Klopp is available to the press while Mourinho is not.
Besides why only add one part of the text? It is so annoying when people do that, like they want someone to look bad:
"We have the memory of what happened in the first stage, but things have changed since then. Real Madrid looks to be stronger to me now."
