It was always going to be a defining summer transfer window for Arsenal.

Following a third consecutive season finishing as Premier League runners-up, the Gunners had no option but to make precise and effective moves in the transfer market — especially with competitors like Manchester City, Liverpool, and Chelsea significantly enhancing their squads.

The club has welcomed six new players, including the crucial No 9 Viktor Gyokeres, a fresh defensive midfielder, Martin Zubimendi, and a group of four new talents designed to foster competition for starting positions.

While this summer’s transfer window has helped them avoid falling further behind their rivals, additional efforts are necessary to ensure Mikel Arteta’s team remains competitive in the hunt for their first league title since 2004.

Mail Sport’s ISAAN KHAN examines Arsenal’s window so far and what could happen over the next month.

1. What have Arsenal done so far?

New sporting director Andrea Berta has effectively managed player acquisitions. Arriving in March after Edu’s unexpected exit, with the club in a transitional phase, Berta has quickly made a substantial impact.

Midfielder Christian Norgaard (£15million), defender Cristhian Mosquera (£13m), goalkeeper Kepa Arrizabalaga (£5m), and forward Noni Madueke (£52m) have all been brought in to strengthen the squad and increase competition among the current stars.

Norgaard provides depth in midfield after losing Thomas Partey and Jorginho, while Mosquera offers versatility in defense and potential for growth at just 21 years old. Arrizabalaga represents an economical yet robust backup option for David Raya.

Madueke is an intriguing signing for the frontline, which has split a fanbase that is anxious about their mixed record of signing players from Chelsea, whereas Zubimendi (£51m) represents a real coup having previously been courted by Real Madrid, Liverpool and Manchester City.

But it’s the capture of Gyokeres (£63.5m) that represents the biggest scalp. Arsenal have been crying out for a striker for years and the situation came to a head in January after Gabriel Jesus and Kai Havertz sustained long-term injuries.

The 27-year-old Sweden striker was courted by a number of clubs and provides the Gunners with something they have long lacked: a finisher. Havertz was their highest league goalscorer last season on nine goals, Arsenal’s lowest in 101 years.

That is a problem that Gyokeres, who scored 97 goals in two seasons at Sporting Lisbon, should fix.

2. What do they still need to do?

Buy a left winger. If Arsenal can do this, it will be one heck of a window for Berta in his first transfer window in the post.

Arsenal still look short of attacking creativity, even with the arrival of Madueke who can play in different positions across the front line. Many times last season Arteta’s side dominated possession but were unable to break down opponents.

But Arsenal’s No 1 priority right now is shifting unwanted players out of the door. Until they can do that, no more pricey signings will be made.

3. Is there enough money and financial headroom left to do what they need?

Arsenal have spent nearly £190m this summer but that doesn’t mean they are done.

Their position with regard to the Premier League’s profit and sustainability rules (PSR) is strong, driven by record revenues (£616m) and profits on player sales (£50m) for the year ending May 31, 2024. It is understood the Gunners could make a loss of at least £85m and still be safe from breaching PSR rules.

However, one of the key focuses of the Kroenke family, Arsenal’s owners, is sustainability and spending within their means. That doesn’t mean they will not back Arteta, but they are keen to bring in money first having only recouped around £10m this summer, with the sales of Nuno Tavares and Marquinhos.

There will therefore be serious push to sell players in this window to ensure they can keep chasing the players they want.

4. Who are they targeting?

Despite the influx of signings, Arsenal’s business is not finished. They remain interested in Crystal Palace’s Eberechi Eze, who they see as an option on the left wing and at No 10 – the position he plays most for Palace in Oliver Glasner’s 3-4-2-1 system.

Arsenal have an open dialogue with Eze’s representatives and the player has a £68m release clause with two years left on his contract. The clause is understood to expire two weeks before the window closes on September 1.

Mail Sport understands a move for Eze will only be possible if significant sales are made, and that any potential move would only happen later in the window.

Another target is Real Madrid’s Rodrygo, who the club do admire, though Eze is higher up in the pecking order.

5. Who is heading for the exit?

Reiss Nelson has showed glimpses of his talent on the pre-season tour of Asia. The same has happened in seasons gone by, where the forgotten man has turned up with a point to prove during pre-season.

But Arsenal are looking to get the academy graduate, and his approximate £100,000-a-week wages, off the books. Fulham are in talks over a loan move for the winger, who has two years left on his Gunners contract but spent last season at Craven Cottage. Arsenal would prefer a permanent move in order to bring in money but a loan would be better for them than Nelson staying.

Oleksandr Zinchenko is also for sale, with Fulham again interested. The Ukrainian, who earns £150,000 a week at the Emirates, has fallen down the pecking order following the signing of Riccardo Calafiori and the emergence of teenager Myles Lewis-Skelly at left back.

Fabio Vieira has been in the shop window for some time. He went on loan to Porto last season and has since been usurped in attacking midfield by Ethan Nwaneri, with highly rated 15-year-old Max Dowman set to push him further down the order. Arsenal are particularly keen to find Vieira a move, with West Ham interested.

Albert Sambi Lokonga is also up for sale. With Leandro Trossard, Mail Sport reported in May that Arsenal have been in talks with the winger over a new deal that would tie him to the club until 2029.

Yet the player is still stalling over the contract and Borussia Dortmund are interested in signing the Belgian, who has scored 28 goals in 124 games for Arsenal since joining from Brighton in January 2023.
