The Gunners are also strengthening their academy ranks with the addition of highly rated youngsters as manager Mikel Arteta continues shaping his squad ahead of the new campaign.
Vieira Pushes for Permanent Hamburg Switch
Fabio Vieira is understood to be eager to return to Hamburg after spending last season on loan with the Bundesliga club.
The Portuguese midfielder enjoyed a productive campaign in Germany, scoring seven goals in 31 appearances and helping convince Hamburg to pursue a permanent deal.
Negotiations between the two clubs are ongoing, although an agreement on the transfer fee has yet to be reached.
Vieira's loan agreement reportedly included an option to make the move permanent for €20 million (£17 million), but Hamburg are hoping to negotiate a lower fee, particularly as the midfielder has only one year remaining on his Arsenal contract.
Arsenal signed Vieira from Porto for around £34 million in 2022, but he struggled to establish himself in North London, scoring just three goals in 49 appearances.
His spell at Hamburg followed another loan move back to Porto during the 2024-25 campaign.
Vieira is currently with Arsenal's first-team squad at their pre-season training camp in Spain as preparations continue for this weekend's friendly against Girona.
Tzolis Makes Instant Impression
New Arsenal winger Christos Tzolis has wasted little time settling into life at the Emirates after arriving from Club Brugge in a deal reportedly worth £34 million.
The 24-year-old has impressed teammates and coaching staff during pre-season fitness testing, with defender Ben White revealing that the Greek international outperformed the rest of the squad.
"Christos has been amazing."
"He came in, did all the testing, and beat everyone. So he is fitting in really well and everyone is really happy for him to be here."
Tzolis also featured in Arsenal's behind-closed-doors friendly against MK Dons, where the Gunners secured a 3-0 victory and the winger contributed an assist.
Arsenal Close to Signing Young Forward
Arsenal are reportedly close to completing the signing of promising striker Mylo Bernard from Crystal Palace.
The 16-year-old forward has already represented England at Under-16 level and is regarded as one of the country's emerging young talents.
Bernard is expected to join Arsenal's Under-18 side initially, although the club hopes he will progress quickly into the Under-21 setup.
The move is part of Arsenal's wider strategy of strengthening their academy. Cardiff City teenager Axel Donczew is also set to join the club after already gaining senior football experience despite being only 16.
Gyokeres Takes Over Dressing Room Music
Summer signing Viktor Gyokeres has reportedly assumed an unexpected responsibility within the Arsenal squad by helping select the dressing-room music during pre-match preparations.
William Saliba has traditionally handled DJ duties, but the French defender is expected to spend time on the sidelines after aggravating a back injury during the World Cup.
Speaking during a fan Q&A on Reddit, Ben White explained the temporary arrangement.
"When Willy isn’t here, the DJ is one of the kitmen or Viktor, maybe."
Arteta Faces Fresh Tactical Challenge
As Arsenal prepare for another Premier League title challenge, Mikel Arteta is set to encounter several unfamiliar opponents in the dugout following a wave of managerial changes across the league.
With clubs including Chelsea, Tottenham, Liverpool and Manchester City appointing new managers in recent months, Arteta will have plenty of new tactical approaches to study before the season begins.
The Spaniard, now the Premier League's longest-serving manager, has already challenged his players to reach "a different dimension" this season as Arsenal look to build on recent progress.
Xhaka Continues to Inspire Arsenal Prospect
Former Arsenal midfielder Granit Xhaka continues to influence the club despite leaving the Emirates three years ago.
Academy defender Callan Hamill cited Xhaka as his footballing role model after signing his first professional contract with the Gunners.
The 17-year-old praised the former Arsenal captain's mentality and professionalism.
"I think it is his mentality and his attitude."
"He’s just a good role model to look up to and I think that’s some type of player that I also base my game off is a player like that and his qualities."
Hamill, who joined Arsenal from St Johnstone in 2025, is regarded as one of the club's promising defensive prospects and has represented Scotland at several youth levels.
