Arteta's men reached the Champions League final with the win over Atletico Madrid on Tuesday, and they have a five-point lead at the top of the English top-flight with three matches to go, while second-placed Manchester City have a game in hand.
Speaking to reporters ahead of Sunday's trip to West Ham United in the Premier League, Arteta shared his message to his players and the Arsenal fans.
"Stay present. Live in the moment. Prepare and show the same level of energy, hunger and desire we have shown all season, or more. We are closer and closer, and everything we do is going to matter," the manager said on Friday.
With the Champions League final against defending champions Paris St Germain set for May 30th, Arteta urged his players to focus on 18th-placed West Ham, who are in a battle to avoid relegation.
"We will have time to prepare and get ready for the final, but now, the full focus and attention to detail, all the energy now has to be put into West Ham. We made that very clear," Arteta said.
"I was in a really high emotional state after the (Atletico) game. We know what it means to everybody.
"But, you have to believe me, straight after that, my concentration, my focus, my energy and my attention was West Ham, what do we have to do mentally, physically, tactically and technically to prepare in the best possible way to go there and win the game."
West Ham, who sit a point below the safety zone, are unbeaten at home in the league since January, holding Manchester United and Manchester City to draws and beating Everton.
"Understanding the context of the game for both clubs is huge. We know the importance of it, we know what we want and what we have to do to win the game," Arteta said.
