Mikel Arteta has promised that Arsenal will continue to make moves in the transfer window, having already added several new players to his squad.
Martin Zubimendi, Kepa Arrizabalaga and Christian Norgaard have all joined Arsenal on their pre-season tour of Asia.
Noni Madueke, who penned his contract on Friday, meanwhile, has been given a break after playing at the Club World Cup with Chelsea.
Arsenal are also reportedly closing in on deals for Sporting CP's Viktor Gyokeres and Cristhian Mosquera, who seemingly bid farewell to Valencia last week.
Gyokeres' 68 league goals in the last two seasons are the most of any player in Europe's top 10 divisions, with Bayern Munich's Harry Kane second with 62 goals in that span. He scored 39 of those last term.
And Mosquera completed more passes (1,822) than any other player for Valencia in LaLiga last season, while he also ranked third in the team for aerial duels won (32).
Arsenal have finished as runners-up in the Premier League for each of the last three seasons, and will be looking to challenge for the crown once again in 2025-26.
"There's still a long time in the window," Arteta told reporters in Singapore.
"And we are seeking still, in terms of numbers, we are short, and we have to improve the depth and quality of the squad. We are constantly looking in the market.
"Until that happens, focus on the players we have and focus on them, and I'm very pleased with what I have seen in the last 10-15 days.
"Ideally, you want it from day one in pre-season. I think we have done very well so far. I'm very pleased with how the club has supported the necessities and improvements that we required in the team.
"I think Andrea [Berta, Arsenal sporting director] and the team has done an excellent job as well, trying to push everything forward. There's a long time to go in the window, but we have still our hopes we can improve the team, and we will continue to try and do that.
"It's like shaking the tree again. Bringing new faces, they bring new excitement, new energy as well. We signed very important players as well.
"I think everybody feels that the heights have to go to different level, and it's what we are seeking."
Asked specifically about Gyokeres, for whom Arsenal are reportedly in negotiations with Sporting after agreeing a transfer fee, Arteta added: "I cannot comment on any player who is not part of our group yet.
"When we have something concrete to offer in any case to any player, we will do that."
Arsenal will face AC Milan and Newcastle United in Singapore this week before heading to Hong Kong to play Tottenham. They begin their Premier League campaign away to Manchester United on August 17.
