Chelsea boss Thomas Tuchel has admitted his displeasure at seeing Kalidou Koulibaly get a red card.

Koulibaly was sent off late in the game against Leeds United, and the experienced centre-back had a bad day in office.

Speaking after the game, Tuchel admitted it was born out of frustration, which shouldn’t be so.

“It is a bit of a reflection of frustration, and it cannot happen,” the Chelsea head coach said.

“We cannot get frustrated in the Premier League. It is a pure joy to play games in an atmosphere like this.

“We should just do it and accept it. It is not okay, and it is not good.”
