Arsenal sporting director Andrea Berta, after a hectic summer transfer window, is maintaining his busy schedule behind-the-scenes long after the summer transfer window's closure.

Mikel Arteta was backed with eight summer signings costing north of £250 million, including the addition of talismanic striker Viktor Gyokeres and England international playmaker Eberechi Eze.

The on-pitch result of these key deals will be crucial in determining whether the Gunners can end their long wait for a Premier League title, which has now spanned 21 years, and the pressure is on Arteta to deliver silverware with no place to hide.

Arsenal take on Nottingham Forest, now managed by former Spurs boss Ange Postecoglou, this Saturday and only a victory will do to recover from their damning 1-0 defeat against English champions Liverpool prior to the international break.

That being said, whilst Arteta has been backed to the hilt, the Spaniard does have injury problems to contend with.

William Saliba and Bukayo Saka will be out for the foreseeable future alongside Kai Havertz, who is expected to be out for many weeks after undergoing knee surgery.

The German's injury prompted Berta to hijack Tottenham's once-advanced deal for Eze, and Arteta couldn't predict the number of months he'll be out for when speaking about Havertz at a recent press conference.

Havertz isn't the only versatile forward out of action right now, as Arsenal continue to wait for Gabriel Jesus' return to the fold.

The Brazilian enjoyed a terrific purple patch of form midway through last season, but unfortunately ruptured his ACL during an FA Cup defeat to Man United in January — ending Jesus' season as he still continues to recover.

Jesus might not be back for Arsenal until 2026, by which time the former Man City striker may not even be at the club anymore.

Arsenal could now sell Gabriel Jesus in January

As per Football Insider and journalist Pete O'Rourke, Arsenal are planning to potentially sell Jesus in the January transfer window, and could be one of two "big name" players to make way alongside Leandro Trossard.

Even once the £265,000-per-week star returns to full fitness, he is expected to be behind both Havertz and Gyokeres in the pecking order — meaning that the writing could be on the wall for Jesus' departure next year.

Given their seismic summer investment, it is highly likely that Berta will be forced to sell if he wishes to add players mid-season — with Jesus and Trossard coming as the most likely sacrifices alongside Gabriel Martinelli.

According to other reports, Martinelli could also be sold by Arsenal in January, as the Gunners maintain an interest in Real Madrid star Rodrygo.
