Wirtz said when asked if Frimpong was responsible for teaching him English: "Yes, he was my neighbour in the changing room, he sat directly next to me and I had to speak English with him. After I finished my school, I didn't speak really good English but he was teaching me a lot and making me speak in more English and better English.
He also spoke of the prospect of joining up with Frimpong once again at Anfield. "I played, I think, three or four years with him," said Wirtz. "He's a really good player, a really good person, a really funny guy. Good for every changing room and also on the pitch, big qualities to attack and to defend. He was then the first one who signed with Liverpool and of course he wanted me to join as well. But I think I made my decision by my own, but it was maybe a small part that convinced me in the end as well.
"I think it's a really nice thing that we can play together again at a new club, at maybe a bigger club, and make the move together. I'm really looking forward to standing on the pitch with him again."
