Leicester took an early lead through Youri Tielemans, but goals from David Luiz, Alexandre Lacazette and Nicolas Pepe helped Arsenal to a 3-1 win, lifting them one place up to 10th on 37 points from 26 games.
Victory at King Power Stadium was Arsenal’s second successive win following Thursday’s Europa League victory over Benfica, which sealed a last 16 berth for the north London side with an aggregate 4-3 result.
“The team is clearly improving, it’s taking a direction I like,” Arteta said.
“We are still giving things to the opposition. It’s something we have to eradicate to give ourselves the best possible chance.
“It’s about how we played against top-quality opposition… I’m proud about winning but obviously the way we’ve done it.
“The way we are playing looks much closer to what we want. The way the team is evolving, we have some consistency in recent months.”
Arsenal travel to face 15th-placed Burnley on Saturday.
