Club captain Aubameyang has had an immensely disappointing start to the season in front of goal and the striker’s frustrations continued this month as a calf injury meant his missed Arsenal’s last two matches with Everton and Manchester City.
Summer arrival Partey has been sidelined since the north London derby with a thigh problem, while Martinelli came off with a knock in the Gunners’ Carabao Cup defeat to City at the Emirates.
On Thursday afternoon, a statement on Arsenal’s official website confirmed Partey would play no part in this weekend’s encounter.
But Aubameyang and Martinelli will be closely monitored in the lead-up to Arsenal’s clash with Chelsea and there’s a chance both could feature versus Frank Lampard’s men.
Arsenal update on Aubameyang, Partey and Martinelli
Right calf. Sustained a slight calf strain in training last week. Auba is working hard with our medical team in order to regain full fitness as soon as possible. Has now joined outside drills and will continue to be assessed regarding availability ahead of Saturday.
Left thigh. Sustained a thigh strain during Tottenham Hotspur (a) on December 6. Thomas is currently unavailable, but is progressing well to now working outside on close ball work, together with the continued focus on his overall fitness rehabilitation.
Right shin. Sustained heavy impact and bruising to right shin during our match against Manchester City on Tuesday. Gabi is recovering well and we hope he will be able to participate in full training ahead of Saturday.
Martinelli was making just his second first-team appearance since returning from knee surgery when he was forced off against Carabao Cup holders Manchester City.
The 19-year-old Brazilian – who assisted Alexandre Lacazette’s 31st-minute header – initially tried to continue following a strong challenge from Zack Steffen.
But the youngster lasted just four minutes of the second half and was replaced by Nicolas Pepe for the remainder of Arsenal’s quarter-final defeat.
Mikel Arteta played down the severity of Martinelli’s injury after the final whistle and the teenager reassured supporters that he was ‘feeling fine and ready to go again’ on his Instagram page.
Hakim Ziyech is yet to make a full recovery from his thigh injury and will play no part in the London derby.
