Daniel Farke says Leeds United's 0-0 draw with Crystal Palace showed why he "would trust my boys with my life" after challenging them to "be heroes".

The Whites ended a game where Dominic Calvert-Lewin missed a penalty with a point after playing the second half with 10 men.

Gabriel Gudmundsson received a second yellow card in first-half stoppage time minutes after Calvert-Lewin failed to hit the target from 12 yards. Yet the only save of note Karl Darlow had to make came after the ball bounced his way off a combination of Joe Rodon and Jean-Philippe Mateta.

"I have to give lots of compliments to my players for a day that has proved why I would trust my boys with my life," said Farke. "I can always count on them.

"We are perhaps not perfect otherwise we would have been a ahead at half-time, but I think it's one of the rare games where the team who has to play for such a long period with an underload (of players) had more expected goals than the home team.

"Even in the second half we were sometimes close to a winning goal. I'm just proud of this performance and how united we were again.

"Before the game I told the lads I was full of confidence in my players.

"In a difficult first half the ball was not that often in play. There were many throw-ins and corner kicks and wide-area free-kicks but I think we had the chances and not just the penalty. Dominic had two good chances before, Brenden Aaronson had a good chance.

"I'm also pretty sure that if we had been allowed to finish the game with the same number of players (as Palace), we would have even won.

"There's a slight disappointment but on the other hand, under these circumstances, a priceless point."

Gudmundsson was sent off for a second yellow card for fouling Ismaila Sarr, with Sheffield referee Thomas Bramall initially appearing to forget he had cautioned the left-back for a foul on Brennan Johnson.

"It was doubtful if it was a foul, it wasn't even close to a yellow card," argued Farke. "There was no pace in the tackle, it wasn't a tactical foul.

"What is most disappointing is he has forgotten that this player was also given a yellow card.

"When you compare this situation with, for example, the situation in the second half when Brennan Johnson was there with a tackle with more pace, a clear tactical foul, this is not a yellow card. And I'm not asking for a yellow-red card for Brennan Johnson.

"If you have one (out)field player less, it means a 10 per cent difference. It influenced the game a lot.

"Thank God we found a way somehow to find a difference."

Farke tried to channel Leeds' sense of injustice at half-time.

"The players are driven by emotions because they knew they had played a really good first half and then lost the player for the second half, also for next week (at home to Brentford)," he explained.

"First of all you need to calm them down, then you also have to take the right decisions, then explain to the players how in the second half we want still to be competitive and still try to attack.

"And also to remind them, if we travel away from here with a point under these circumstances, or perhaps even three, it's more or less the day where heroes are born."
