Thomas Tuchel confirms that Chelsea forward Christian Pulisic has tested positive for Covid-19 which rules him out of the London derby against Arsenal this weekend.
Pulisic had played in the European Super Cup and the first round of the Premier League, and taken a goal in the game against Crystal Palace.
Thomas Tuchel says: "Unfortunately he had a positive test and needs to follow the protocols. He's not been training and is not available for the game against Arsenal."
