Kepa has been linked with a loan move back to Spain and Sevilla are interested in him.
Asked about the speculation around Kepa's future and what he wants to see from the goalkeeper for the remainder of the season, Lampard said: “I keep saying the same, I am not going to talk about any potential what we may do at the end of the season or not. I am going to focus on what is in front of us.
“And with Kepa, a lot has been spoken about him this season. All I want from him, as I want from all the players, is the right mentality, attitude and approach to the games. I am absolutely certain I will get that from all of them.
“Obviously to try and do his job as well as he can do. And I am happy with him, and that is how we keep working. I am not going to talk about what may be at the end of the season."
