Both Fuan and Smith-Royce are back on the training pitch, but Arteta wants to be cautious about right-backs.
Both Fuan and Luo missed the game against Watford, the former suffering from a leg injury and the latter contracting the new crown.
Kenyo Fuan has returned to training but has not yet fully recovered, with Arteta's remarks suggesting they would not let the right-back play too soon.
"He needs to keep training for a while so that we can minimize the risk of a recurrence of an old injury to the same muscle because there are concerns about that and we have to keep him out of the field first," Arteta said.
'He suffered a calf injury and after that he recovered quickly and we got him on the pitch, probably a little too quickly, I don't know.'
'His old injury recurred and then one day he came back to the training ground and he felt it again and yes, it was disappointing because he's always been very important to us.'
As for Smith-Rowe, the situation looks more positive. Similar to the Japanese defender, he also returned to the training ground but had the opportunity to play this weekend.
"He overcame the new crown and is feeling good now," Arteta said.
"He has been in training twice and hopefully he can find rhythm and consistency and not miss games because he is really important to us. We need him. ”
Arsenal are set to play three games in the next seven days, so they need as many squad options as possible.
There are still plenty of people in some positions, such as Pepe, who is ready to take over Saka.
But without Smith Rowe on the left, without Anan Kenyo on the right, it would be difficult to find a replacement if Martinelli or Suarez needed a break.
Liverpool will face Arsenal next Wednesday, with Klopp hinting there are some cases of COVID-19 in the squad.
Speaking at a pre-match press conference against Brighton, Klopp said some players and staff may not be involved in the game due to the positive coronavirus.
"Covid-19 is not over except for injuries, so we have these situations," Klopp said. "We tried everything we could to avoid it, but it was unlikely. Players and staff have no symptoms but are unable to compete. ”
Hearing this remark, Arsenal fans will have some associations, because the League Cup with Liverpool in January was postponed.
Fortunately, there is no information yet that the outbreak within Liverpool is enough to postpone the match.
Arsenal really can't stand more postponements anymore. With just over two months left until the end of the season, the Gunners have 11 league games to play, two of which are postponed games against Tottenham and Chelsea.
The match against Tottenham hotspur should be relatively easy to schedule, and at the moment both clubs have no other competitions to tie in, just choose a midweek in April or May.
But the match against Chelsea could be more difficult to schedule, with the Blues currently playing in the third tier. The same applies if the match against Liverpool is postponed.
