Chelsea captain Cesar Azpilicueta said he felt sorry for Reece James after the youngster was sent off in a 1-1 draw with Liverpool on Saturday.
Thomas Tuchel’s team took the lead with a header from Kai Havertz and looked very dangerous up front.
But just before the break, the game changed when the young England international was deemed to have rolled over the line.
The referee initially missed the incident, but approached the VAR screen and immediately decided to award a penalty and a red card.
Mohamed Salah converted Liverpool’s penalty to tie the draw for the Reds just before the halftime whistle.
Speaking to the BBC, Azpilicueta described the decision as difficult, saying: “It’s difficult. Sorry for Reece. The referee received advice from the VAR to give it to him. He went to the screen to watch a replay.
“We received a double penalty, a red card and a penalty, and two yellow cards in the same action. We are angry.
“But you have to calm down and find a way to fight together as a team. I think the team struggled and maybe we had the two best chances in the second half.
“I would like to know if he touches the ball with his leg first, which can be [a mitigating circumstance]. You already know the rule of handball, we had a meeting … it’s difficult.
“In this position, the ball is on the line and it has just hit the ball on the leg and then on the arm.
“I understand that the arm is a little further from the body, but we also can’t run with the arms close to the body. So of course, as a defense, it’s very difficult and deceptive. “
