Kepa featured in last night's 1-1 draw, having been blocked from joining Real by Zidane in January.
Afterwards, asked if he was sorry with his decision, the coach stated: "How can I think that? Not at all, if I made the decision not to bring a goalkeeper in the middle of the season? For me that does not exist.
"When I start a season I start with three goalkeepers and finish with three goalkeepers. And nothing else, I do not have to say anything else, the opposition goalkeeper is very good but he is not my player and in the middle of the season I did not need a goalkeeper."
