Arsenal are making serious moves behind-the-scenes as new sporting director Andrea Berta looks to make a real impression on English shores, with the 53-year-old thought to be closing in on another target.

The Gunners confirmed Kepa Arrizabalaga's arrival in N5 earlier this week.

The now-ex-Chelsea goalkeeper comes in as Berta's first official signing since he replaced Edu in late March, but Kepa is widely expected to be followed by Real Sociedad midfielder Martin Zubimendi, who could even be announced as a new Arsenal player on Thursday (Team News and Ticks).

After agreeing a deal for Brentford captain Christian Norgaard recently, which could reach up to £15 million, reliable journalist Fabrizio Romano now says that all the necessary paperwork has been exchanged for his transfer to the Emirates Stadium.

Mikel Arteta and co will ideally welcome the signing of Valencia defender Cristhian Mosquera as well, as talks remain ongoing with the La Liga side in an attempt to strike their fourth deal of the window. Valencia did attempt to offer the 21-year-old a new contract to ward Arsenal off, but he's apparently determined to join Arteta's side.

"Cristhian Mosquera’s plan remains clear: he wants to join Arsenal project despite new contract proposal from Valencia," said Romano on X.

"Full focus on negotiations with #AFC as personal terms are agreed, and new bid will be needed after opening one for €14m, rejected."

Berta has many plates spinning right now, with Crystal Palace star Eberechi Eze also firmly on their radar.

Arsenal talks with Eberechi Eze "well advanced"

Earlier this week, it was reported that Arsenal held "positive" talks with Eze's representatives last weekend, and like Mosquera, he's pretty keen on the idea of joining.

Now, according to French newspaper L'Equipe, Arsenal's negotiations with Eze are "well advanced", and all that is really left to do is trigger the England international's release clause to strike a full agreement.

This comes after "further moves" in "recent hours", as the outlet reported on Wednesday afternoon, so it appears Berta and co have upped the ante in their pursuit since their weekend discussions.

It is worth noting that Palace have no intention of accepting an offer lower than Eze's £68m clause, with Arsenal told the exact price needed to make the 27-year-old their next major signing.

It is currently unclear what the ex-QPR star is demanding in terms of salary, with Eze on a reported £100,000-per-week in south London right now, but it could end up being quite a costly operation overall.

However, after his best-ever season at Palace with 14 goals and 11 assists in all competitions, there is little denying he'd seriously upgrade Arteta's squad.

"His journey has been unique," said pundit Rio Ferdinand on TNT Sports.

"He’s had disappointments in his academy life, released from clubs, found a new journey and a different pathway for himself. He’s got to this level and now he’s an England international.

“This kid, no disrespect to Palace, could go on and play for one of the top teams. He’s got that individual brilliance; he’s got the awareness when he’s dribbling to keep his head up and bring others into play. I speak to other players that play against him, and they say he’s such an elusive player, unpredictable in the way that he carries the ball, but also [his strength]."
