Sevilla coach Jorge Sampaoli was left frustrated by their Champions League defeat at Leicester City.

Sampaoli branded it the club's "most painful defeat" in recent years.

He said: "In the first leg we deserved a bigger lead. Today's result is undeserved, but football has these things. In this round-trip they resolve the details and we were worse than the opponent."

On Samir Nasri's dismissal, he added: "I do not know, but I hope that the quality of Nasri as a soccer player will continue helping us. He contributed a lot. I do not know about the expulsion. Because of the frenzy of the match I'm far away and I could not see it. He is a player who gives us a lot for us and I hope he stays."

Nasri is on a season-long loan from Manchester City.
