According to Sport, Arsenal have confirmed Saliba will be out for a long time, and Mosquera is expected to fill in at center-back.

A golden opportunity to secure his place.

The former Valencia player has already shown potential in pre-season and started in Arsenal's last warm-up match, a 4-1 win over Girona. Last season, he played 35 games for the London team. Arsenal are the reigning Premier League champions and Champions League runners-up, which shows that coach Mikel Arteta trusts his abilities. If Arsenal ultimately do not enter the transfer market to strengthen their defense, Mosquera has a good chance of becoming a regular option at center-back.

However, this opportunity also comes with huge responsibility. Maintaining a high level of competition in the Premier League and Champions League requires stability, character, and the ability to perform under pressure, qualities Mosquera has begun to demonstrate since arriving in London. Now, with Saliba's absence, the Spanish center-back has the opportunity to establish himself as a regular starter and take a crucial step in one of European football's most ambitious projects.
