The Gunners swept aside their Irish opponents in their Europa League on Thursday, cruising to an easy 3-0 win.
Arsenal head to Old Trafford having lost their previous two Premier League games against Manchester City and Leicester City.
And asked if players could have played their way into his plans after Thursday’s win over Dundalk, Arteta replied: “Yeah, they are always in the frame to play. It is not if we lose or win, it is what they bring to the team.
“How they train, what they are showing. Results at the end are consequences of many things, but individually how they do things is what determines whether they have the opportunity to play or not.”
Another player who got a chance to impress on Thursday was forward Folarin Balogun, who came on for his debut.
The 19-year-old is into the final year of his contract at Arsenal and he is yet to agree fresh terms.
Balogun has attracted interest from the likes of Brentford, Sheffield United and Southampton, but Arteta says he can have a future at Arsenal.
“It is a player that I really like,” said Arteta. “Obviously I got this situation a little bit later than what I would like, because I wasn’t here when everything started to develop.
“But he is a player I would like to give chances to, this is why he was in the squad today. I am showing that we count on him, we believe in him and, if he wants, he is going to have a future at the club.”
Arsenal’s win over Dundalk puts them top of Group B and they are now in pole position, along with Molde, to qualify for the knockout stages of the Europa League.
“We made it look easy because we were very disciplined, took it seriously and were at it from the beginning,” Arteta said.
“We made a lot of changes, gave opportunities to other players and I think they performed well.
“We have a large squad and I wanted to give opportunities to everybody. Today they showed they were prepared when I need them and today they made it more difficult for me for selection.
“Sometimes it is about the quality, sometimes it is about the tactical plan for the game. I am very pleased with the performance today.
“After losing the way we lost against Leicester it was painful. It took us a few days to react, but it was good to respond straight away with a win and now we go to Old Trafford and try to win again.”
