Christian Pulisic reportedly tested positive for COVID-19, he will miss the second match of Premier League on Sunday against Arsenal.
Discussing Chelsea squad to face Arsenal, Tuchel said: “Christian is unfortunately pretty easy to explain. He had a positive test and needs to follow the protocol, so he was not in training and is not available for the game.
Speaking about other players, Tuchel said N’golo Kante Hakim Ziyech are on training, ready to face the Gunners.
“Hakim and N’Golo were both in training today and had absolutely no problems. We need to have another more physical training session tomorrow with them but right now it seems very positive that both can be in the squad for Sunday.”
Chelsea’s manager also said Romelu Lukaku is available and on training to face Arsenal after completing Inter Milan’s transfer. He said, “We are hoping he is on the pitch for Sunday and things look like it.”
Chelsea will travel to Arsenal as favourites following the Gunners’ 2-0 defeat at newly-promoted Brentford in their first Premier League game of the season, and Tuchel is expecting Mikel Arteta’s side to play up to their “underdogs” tag.
Arsenal have also been hit by a Covid outbreak that has impacted several players, including captain Pierre-Emerick Aubameyang, and Tuchel said: “I don’t know what [their] team will be – it’s a difficult one to predict.
“They can play maybe the underdog role here because of the complications they have with the Covid situation, the difficulties they had in the first match.
“I think they will try to put themselves into the underdog role and fight from there, which is fair enough.
“It’s on us to be absolutely focused and well aware of everything that they will ask us. They can hurt anybody if you’re not concentrated.”
