Arteta expressed his enthusiasm about welcoming Mosquera into the Arsenal fold, praising the player’s maturity and positional awareness despite his young age.
"We're delighted to welcome Cristhian to Arsenal. As a 21-year-old defender, Cristhian has already performed consistently well with significant experience in La Liga," he said. "He is an intelligent player with good pace, who can play centrally and on both sides. He is a young player with exciting talent and enormous potential, who will fit well into our squad as we continue to prepare for next season. Cristhian adds good quality to our squad, and we look forward to working with him and making him feel at home with us. From all of us, we welcome Cristhian and his family to the club.”
