Unai Emery will decide on Saturday whether Nicolas Pepe and Alexandre Lacazette can feature against Newcastle on Sunday.
Pepe completed a club-record £72m move to Arsenal from Lille last week and has been training with the first team, while Lacazette has resumed training over the past few days after suffering an ankle injury in a pre-season friendly against Lyon.
The Arsenal boss says both will undergo late fitness tests ahead of Sunday’s game at St James’ Park.
“We played the pre-season progressively, including the players who came in late. On Sunday we will start with the players that I am convinced are 100 per cent,” he said.
“For some players it is impossible to achieve that performance because they arrived late or are now training after being injured.
“Lacazette trained yesterday and today but I don’t know know if he can play on Sunday, we will check tomorrow.
