Speaking to Liverpool's club media, Diaz said: "It’s no secret, we didn’t finish as well as we hoped. For us, it was crucial to win the league and all the competitions we were in. Unfortunately, the results lately could not be achieved.
"We fell [behind] as a team, but we made a decent season, both individually and as a group. There are many things to improve so we can have a perfect season. But I’m happy and content to be here."
Diaz also praised the Liverpool fans for creating a chant for him, as he said: "It’s something beautiful and special because every time we go out to give it our all. To uphold the institution, the club. To do what I came to do from the first moment I arrived.
"I always wanted to perform well. I always wanted to be one of the best, trying to respect everyone. Seeing the fans sing that song, that beautiful song, leaves you something very nice marked for you, to take as a memory.
"I’m very happy. I thank them very much for what they are doing. I always go out happy to the field because I know I have their full support."
