Osasuna, the La Liga team, is looking for a new left-back and Kieran Tierney, a Celtic player, is on their list of targets. The Spanish club has been trying to sign Aihen Muñoz from Real Sociedad, but that move has stalled. Osasuna is now reviewing other names, with Tierney and Diego Rico in the frame. A new report from Spain says the club's sporting director has been asking about the Celtic defender in recent hours. ### Why Kieran Tierney makes sense for Osasuna after his return to Celtic? The Scottish defender has played 53 games for Celtic in the past season and has been one of the most consistent players in the team. Tierney also has experience in La Liga, having played a season on loan at Real Sociedad in the 2023-2024 season. ### What's next? Osasuna is still waiting for Muñoz, but if that doesn't materialize, the club may look at Tierney. However, Celtic has all the cards in their hand, as Tierney signed a five-year contract in 2023 and is tied to the club until 2030. Osasuna is currently 9th in the La Liga table, with 39 points and a -1 goal difference in the 2025 season. The team has scored 37 goals and conceded 38 in the current season. Osasuna is 40 points behind leaders Barcelona and their next game is at home against Sevilla on February 28, 2027.
