Arsenal's manager has voiced fears that his squad's chase for titles this season is being jeopardized by a concerning circle of fitness setbacks and a grueling schedule.
Key midfielder Declan Rice did not travel for the midweek trip to face Club Brugge due to sickness. Meanwhile, forward Leandro Trossard and center-back William Saliba are still unavailable.
There was, on a brighter note, better news regarding Gabriel Jesus, with the South American forward registered to their Champions League squad. He replaces the injured youngster Max Dowman, who suffered an foot problem.
"Training, no because we don't have time to train. But clearly the fact that you are without players, you are loading other players more, there's a knock-on effect to that and it's a truly dangerous cycle."
Dowman's issue is the latest in a extensive list of injuries for the North London side. Since the start of last campaign, they have suffered 95 injuries, the second-highest total in the English top flight.
Arteta dismissed the idea that training intensity were to blame, pointing to a shortage of time for drills. He highlighted the strain on fit players, some of whom have featured over 150 matches in two seasons.
Even after a major summer investment exceeding £250 million, Arteta insisted the team is unlikely planning to enter the January recruitment market.
"At the moment we're just concentrating on bringing the players back and hopefully it will be a question of a short time," he said. "It's clear how important those coming weeks are going to be."
The squad experienced their first defeat in 18 games at the weekend, reducing their advantage at the summit of the Premier League to two clear points.
Focus now turns to the European stage, where a sixth group win would virtually guarantee a knockout phase place. Winger Gabriel Martinelli could make a club record by finding the net in a fifth straight successive European fixture.
"We are frustrated with the outcome, but we have to keep going," he said. "It's not like all is going badly because we lost one game. So we stick together."
