Arsenal host Brendan Rodgers' Leicester on Saturday in north London and the Gunners have won their last three match-ups against the Foxes, only conceding one goal.
The injury report
"The injured players have been reintegrated back into training, they are in different phases and some of them will be in the squad tomorrow.
One player who could make the starting lineup is Scotland's set-piece specialist, Tierney.
"He played 15-20 minutes last weekend and he did really well after being out for a long time after the knee injury, he looks in perfect condition now and ready to work," the manager said.
"He needs to stay fit, train well and play at the level he can perform at."
Reiss Nelson, however, has picked up an injury that could force him out for a while.
"He felt something in training, we scanned and the doctor came back with some bad news, It's a muscular injury and hopefully he will be back soon.
"We need to do some more tests and then hopefully next week we will have some more information."
"A 'fantastic' week"
Arteta seemed optimistic as he recalled a productive week in North London.
"The boys have been training fantastically well, the weather conditions have helped a lot, we've had a busy week with some players leaving the club," he said.
But more deals could materialise before the transfer window shuts, Arteta suggests.
"We had to move the squad a lot and we are still willing to finalise the squad the way that we want, we can add in something great but there are also a few players that we need to find the right game plan for them."
When asked if the recent rumours that Man City might try to take Tierney off their books, the manager bluntly replied:
"No and you know that I'm not going to be commenting on individual players."
Arteta's now infamous 'non-negotiables' – rules everyone at the club must abide by – were also discussed.
"It is the first thing that we talk about, what we are going to expect from them and what they are going to expect from the club, what our values are, how we like to behave and that we are here to have enjoyment, it's our passion and its what we love doing and in order to do that we have to get on well," Arteta said.
Pierre-Emerick Aubameyang is believed to have been stripped of the captaincy and left out of the first team squad as a result of numerous breaches to these 'non-negotiables'.
Arteta, however, had only good things to say about his former captain.
"I'm really happy with where we are as a club and the people we have here.
"Aubameyang is an exceptional player and was brilliant for us."
"We'll have to adapt to the heat"
An unusual challenge both Arsenal and Leicester will face on Saturday is the heat, which could hit a devastating 36 degrees.
"We have to adapt and be prepared mentally to play in those conditions as it's not something we do normally, we have the five subs as well which is very helpful."
With temperatures set to test both sides in north London, it will be a new challenge for Arteta and Rodgers to navigate.
