Arsenal are not alone in their admiration for the commanding centre-back. Premier League rivals Liverpool and Manchester City have also been monitoring Mosquera’s development, according to TBR Football, who first linked Arsenal with the player back in November. Scouts from all three clubs have watched the player extensively over the past year, impressed by his physicality, composure on the ball, and maturity beyond his years. Given that interest is only likely to increase as the transfer window progresses, Arsenal may feel a sense of urgency to return with an improved offer sooner rather than later.
