“I don’t know the extent of it. For Thursday, David [Luiz] will be out, Kieran [Tierney] will be out and then with Emile [Smith Rowe] and Martin [Odegaard], we don’t know yet. We’ll have to see how Bukayo develops in the next few days.
“I hope Pierre-Emerick [Aubameyang] can be back for Thursday – he was unwell yesterday and couldn’t train but hopefully in the next day or two he can be better.”

Arsenal’s opener was a goal of real beauty as Dani Ceballos’ deft backheel flick eventually put Lacazette through on goal to slide the ball beneath Aaron Ramsdale.
It was not quite of the level of Arsenal’s much-celebrated team goal against Norwich in 2013, scored by Jack Wilshere, but it had many of its hallmarks.
Arteta added: “It was a typical Arsenal goal. It was of a high quality and the movement was really good. Laca is playing really well at the moment – he’s full of confidence. He needs to keep doing it right up until the end of the season.
“In the last six or seven months, I’ve seen a big change in the way he interacts with people and the way he interacts with his team-mates. I have seen the leadership he has taken onto the pitch and that’s really positive. He’s a player with huge experience and we need his type of character in the team.”
The Gunners doubled their lead midway through the second half when John Lundstram sloppily surrendered possession to Nicolas Pepe while attempting to play out from the back and the Ivorian’s driving run and shot saw Ramsdale parry the ball out for Martinelli to tap into an empty net.
It was the teenager’s first goal in 15 months following a serious knee injury, but Arteta reiterated the need to be patient with the forward amid a clamour for him to be handed more regular starts from supporters.
“Of course, I’m delighted with him but I’m asking you to be patient as we have a lot players who are 19, 20 years old. They’re compared with other players of similar ages at Premier League clubs towards the top end, but it’s not common. Gabby is having the right path and the right development.
“He’s got an incredible attitude and talent, and has his entire future in front of him. What we need to do is manage that and try to give him the right amount of minutes and the right games to develop and get better.”
