Mikel Arteta gives Arsenal injury update after Riccardo Calafiori and Martin Odegaard problems
Mikel Arteta has confirmed Ben White and Riccardo Calafiori are two new injury doubts to come out of their 4-0 win over Wigan Athletic.
Bukayo Saka replaced Calafiori in the starting line-up, with Ceadach O'Neill being called up to the matchday squad and coming onto the substitutes bench. The winger played until half-time, when Viktor Gyokeres entered the action with Arsenal leading their League One opponents 4-0.
Late in the second half, White came off with what appeared to be cramps as Martin Zubimendi replaced the defender. There was also a surprise change of goalkeeper, with Kepa Arrizabalaga coming off for Tommy Setford to make his debut.

Asked about Calafiori and White, the manager said: "Yeah, he and Ben are the only doubts. We have to wait and see in the next 48 hours how things develop."
Addressing the availability of Martin Odegaard, Arteta added, "Martin, we'll have to wait and see. He picked that knock on the action when we conceded the goal, and he wasn't fit for today."
On whether he was worried about the squad's depth, he said: "Yes, and especially because we are going through, before it was the strikers, then it was the defenders, now it's the midfielders.
"We are still coping with that, but we need some players back and fit and to give us as well not only numbers but different options in relation to the opponents that we have, so the quicker the better."
Arteta also explained the change of goalkeepers. He said: "I think everybody has to feel that he's got a chance, and if there are players, one of them will be Tommy for his attitude and the way he helps everybody every single day. So we had a chance to play in some minutes, we have to try to do it, and I think we're very happy."

Marli Salmon also replaced William Saliba on the hour mark for his home bow at Emirates Stadium. At the same time, Leandro Trossard came on for Noni Madueke, who put the Gunners in front after 11 minutes.
Eberechi Eze assisted his England teammate for that opener. The midfielder also set up Gabriel Martinelli for the second seven minutes later.
The third was an own goal from Jack Hunt after Gabriel Jesus inadvertently directed a Saka cross onto the Wigan defender's head. A fourth then came inside the opening half an hour after Christian Norgaard assisted the Brazilian.
Arteta was happy overall with the match. The manager said: "Very happy with the result and especially the performance, the way we started the game. You really want to show how much you want it when you play against this kind of opposition in the cup, and we certainly had that attitude.
"And then I was a bit surprised with the level of cohesion and connections very early in the match because when you make that many changes, that can be a part of the game that can be lacking, but certainly it wasn't, and we scored some very, very good goals, and I'm very pleased with that."
