Pierre-Emerick Aubameyang will be assessed on Friday ahead of Arsenal’s match against Everton after falling sick.
Having been signed for a club-record fee from Borussia Dortmund on Deadline Day, the Gabon international was poised to make his debut at the Emirates on Saturday evening.
However, Gunners boss Arsene Wenger revealed on Friday that his new forward is recovering from a sickness bug.
“I have to assess how well he is physically today and how well he feels,” said Wenger.
“He had a fever, so he could not practice a lot. He started yesterday, but was still not completely well.
“I have to assess with the medical department how fit he can be.”
The Aubameyang deal has been welcomed by Arsenal fans following the departure of Alexis Sanchez to Manchester United and Wenger says the 28-year-old was ready for a move to England.
“The Premier League is a challenge for every big player today,” said the Frenchman.
“That is where everybody wants to play.
“I have known him for a long time, he has played against Arsenal many times.
“He likes the way we play football and I believe he needed a new challenge. We were the ones who could offer that to him.”
