Manager Mikel Arteta has said that Arsenal's summer signings have added a new dimension to the squad after their 6-0 Premier League win over Sheffield United on Monday.
Declan Rice and Kai Havertz, roped in from West Ham United and Chelsea in the summer, got on the scoresheet as Arsenal matched their biggest Premier League away win with an impressive performance at Bramall Lane.
Arsenal have registered victories in their last seven league games and are third with 61 points, two points behind table-toppers Liverpool.
Asked if the players brought in the summer had positively impacted Arsenal, Arteta told reporters: "Yes for sure.
"Obviously picking the right players that could bring something that we didn't have to the squad, and they're certainly doing that and improving every single player, and the mechanisms and culture around the team.
"They are doing that but there's still the most important part of the season ahead and we know that that's the case."
He also gave an injury update on Bukayo Saka and Gabriel Martinelli, who did not feature the full 90 minutes.
"(Saka) was feeling a bit sick and as well we have Fabio (Vieira) who we have to give minutes," Arteta said.
"It was great opportunity (for us) and then we had a little issue with Gabi Martinelli as well, he had a slight cut on his foot and we have to wait and see how he is."
Arteta added that Japan international Takehiro Tomiyasu is "very close" to making a comeback from a calf injury.
Arsenal next host Brentford in the Premier League on Saturday.
