The left-back spent two seasons playing under Iraola at AFC Bournemouth before signing for the Reds a year ago.
Iraola followed the same path this summer when he was appointed Liverpool’s new head coach and Kerkez believes the footballing philosophy of the Basque and his backroom staff matches up well with the principles of their new club.
“I’m really happy they’re here,” the Hungary international told Liverpoolfc.com.
“I think we had really great times together in Bournemouth and when I saw that he \[Iraola\] was coming, when I heard about it, I was obviously really happy. I know him, I spent two years with them in Bournemouth.
“They know me, I know them and I know that they can bring a lot to the club – especially Andoni with the playing style, with the energy and how he wants his team to play. I think it suits Liverpool and I think it’s going to be really exciting times ahead.”
Kerkez went on to detail what it is like to play for, and be managed by, Iraola.
He continued: “He’s a nice person, obviously. He is nice. He lets you know straightforward what he wants from you, then it’s up to you to do it. I mean, if you don’t do it, you’re not playing, simple as that. But he is good. Like I said, he lets you know what you need to do for him.
“He’s maybe not much of a talker, but he shows fully his emotions a lot, you can see on the sideline and everywhere that he’s really, really energetic. He is coming from Bilbao and you know their mentality is also like that, so like I say, I think he’s a really perfect boss for Liverpool and how he wants his team to play.
“We just have to make a good pre-season and obviously listen to him, listen to what he wants from us and I think the team is going to be in good shape.”
