Leeds boss Javi Gracia defended his players after their defeat at Arsenal.
The Gunners cruised to a 4-1 win on Saturday.
Gracia said: "In my opinion it was more competitive [in the first half]. After conceding an early goal [after half-time], it was difficult for us to manage the second 45 minutes.
"It's not easy. My players tried, but the game changed [after the penalty] and it was difficult for us. I don't have any problems with my players.
"I know we're going to compete in the best way in our next game. We don't have time to complain. We have to prepare because in three days we play another game [at home to Nottingham Forest]."
