Leeds United manager Javi Gracia has defended his players after harsh criticism this week.
The Elland Road team has conceded 11 goals in the past two Premier League matches.
During those games, eight of the goals they conceded occurred during the second half.
"I can understand the supporters because in some parts of the last game and in the game before in the second half against Palace, there were some moments when you could have that feeling [that the players lacked desire]," Gracia said in his pre-match press conference.
"But I have to defend my players because I know they tried. Sometimes these moments are difficult to manage, and to deal with that is something which is more than a lack of desire for sure."
