"I have no doubts, it's just a matter of time," Alonso said in a pre-match news conference on Monday, when asked about Wirtz. "It's a big chance for him, coming to Liverpool after so many years in Germany, and being there his whole life."
Alonso added that Wirtz inadvertently played a role in Madrid appointing him to replace Carlo Ancelotti at Santiago Bernabeu.
"He needs to adapt, but he's a really special player," Alonso added. "He's competitive. One of the reasons I am here is because of Flo. Hopefully not tomorrow (Tuesday), but I hope soon he'll show his quality and his class."
