Indeed, Hans Wirtz says son Florian is performing well for the Reds, despite the criticism.
"I only take the criticism from the former internationals in passing," he told the Kölner Stadt-Anzeiger. “Florian is a young man who wants to prove himself in a new environment.
“Less than a third of the season has been played. So far, everything is going as expected; it's a completely normal settling-in process, entirely independent of any transfer fee.
“And if you look at the statistics more closely, you can see that Florian's stats regarding his involvement in the game are already quite good; only assists and goals are still pending.”
He continued: “We all really enjoyed our time in Leverkusen. Whenever I pass the BayArena, I always feel a little nostalgic. But that’s just my personal feeling.
“Florian consciously took a step to become an even better footballer. And he doesn’t regret it at all.
“He’s doing well in Liverpool, he looks forward to every training session, and he’s settled in with the team. We’re 100 percent satisfied with how things are going so far.”
