Arsenal are set to officially unveil Cristhian Mosquera as their latest signing, with the young defender already training alongside his new teammates in Singapore. The 19-year-old has joined the Gunners from Valencia in a deal believed to be worth around €20m, as Mikel Arteta continues to strengthen his squad for the new season.
Mosquera’s arrival has not yet been formally confirmed by the club, but multiple sources suggest an announcement is expected later today. The Spain youth international has already been spotted at Arsenal training sessions during their pre-season tour, suggesting the deal is complete and integration is underway.

Mosquera joins Arsenal’s growing list of summer additions
Should the announcement come as expected, Mosquera will become Arsenal’s fifth major signing this window. He joins Martin Zubimendi, Noni Madueke, Christian Norgaard, and Kepa Arrizabalaga as part of a reshaped squad built to compete on multiple fronts.
The 6’2″ centre-back brings calmness in possession, aerial presence, and strong recovery pace traits Arteta has clearly prioritized heading into a Champions League and Premier League double campaign. With question marks over defensive depth last season, Mosquera could play a key rotational role, especially in cup and midweek fixtures.
Why Arteta sees Mosquera as a long-term project
At just 21, Mosquera arrives with potential rather than pressure. Arteta and Berta are believed to see the Spaniard as a long-term fit, someone who can develop behind senior figures like William Saliba and Gabriel Magalhães.
The defender’s early arrival on the tour also helps ease adaptation, both tactically and socially. With players like Declan Rice showing leadership in integrating new signings, Mosquera’s transition looks well managed from the start.
Final thoughts
Arsenal’s rebuild continues to gather pace, and the addition of Mosquera could quietly become one of the smartest deals of the summer. Announcing him during the Singapore leg of pre-season sends a clear message: the club is moving fast, thinking long-term, and giving young talent a platform on the biggest stage. Expect the official reveal soon, the defender is already part of the group.
