"I am unlucky because a number of players have been injured, and it is true that this is part of the game, but it makes the job of any coach difficult," he told the media after the latest defeat.
"Al Hilal are a big team that I have faced before in the Club World Cup, and when you coach a team like them your job becomes easier. For example, I should not tell [Joao] Cancelo how to play crosses or tell Mitrovic how to score.
"I only had five training sessions and three matches with Esteghlal, and I feel that we have started to develop, and I accepted the job knowing the problems surrounding the team."
