Confidence has been low around Emirates Stadium after a poor run of form which has seen the Gunners slip to 15th on the Premier League table, but Arteta believes his side must remain positive and pick themselves up instead of pointing fingers at each other.
Chelsea have not been in great form of late despite putting back-to-back defeats behind them to beat West Ham United 2-0 on Monday but Arsenal will be hoping to win for the first time after failing to do so in their last seven league games.
The Arsenal manager said: "At the moment, to keep the team together, to keep the team alive and to be a team, not a group of players, it takes a lot of energy because when you are losing football matches you have to lift them up, to get them together.
"You have to get them all being positive to each other, to not blame each other or any external factor when things are not going well.
"The best thing to do when you have a situation like that is to have the possibility to do things outside of the site, get them together in a change of environment, but at the moment, with Covid [restrictions], we cannot do it and probably we are not going to be able to do it in a while.
"We have to try other ways, but I have to say the players are really putting in a lot of energy enthusiasm not to lose what we are building, but it takes a lot of energy because we are losing games.
"Every game is a lot of weight on your shoulders, it's a lot of disappointment and people are suffering. We are hurting and suffering and we have to get back, start believing again and try to push the players, then they respond and are excited for the game.
“The best medicine, better than anything than can happen outside of our facilities, is to win against Chelsea."
