Pamplona, Spain – As the 2025/26 LaLiga season approaches, all eyes are on Osasuna’s newest recruit, Valentin Rosier, who is poised to make his competitive debut against reigning champions Real Madrid at the Santiago Bernabéu on his 29th birthday.The highly anticipated match, a rematch of the 2023 Copa del Rey final, marks a pivotal moment in Rosier’s career and a notable test for Osasuna.
Early Career and French Foundations
Born in Montauban, France, Rosier began his professional journey in the French fourth division with Rodez AF during the 2015/16 season. He quickly ascended to Ligue 1, joining Dijon in the summer of 2016. His initial season was hampered by ankle injuries, limiting him to just four appearances across all competitions.
However, Rosier rebounded in 2017/18, establishing himself as a key figure on the right side of Dijon’s defense, occasionally filling in at left back. His consistent performances earned him a call-up to the France under-21 national team in 2018, where he played alongside future stars like Dayot Upamecano, Christopher Nkunku, and youssouf Fofana.
Did You know? Rosier initially started his career as a winger before being converted to a right-back by his coach at Rodez AF.
“When I was 18 in Rodez,my coach told me,’I want you in the team,but you have to play right back.’ I just wanted to play,and I’ve been a right back ever sence I went professional.”
Rosier reflects on the demands of the fullback position, stating, “Whether it’s a right back or a left back, fullback is the most difficult position in football. You have to attack, you have to defend…It’s significant to make assists, but it’s also critically important to save the team with a last-gasp tackle.”
Turkish Success and Portuguese Interlude
A foot injury and a toe injury briefly stalled Rosier’s progress in early 2019, but it didn’t deter Portuguese giants Sporting CP from signing him for €7.5 million, alongside Mama Baldé. His debut season in Lisbon was disrupted by further foot problems, resulting in only 16 appearances.
Rosier found renewed success in Türkiye, joining Beşiktaş in Istanbul. He quickly became a standout player, contributing three goals and seven assists in 37 matches and helping the club secure a domestic treble. His exceptional form earned him a place in the 2020/21 Süper Lig Team of the Season.
“When you are at Beşiktaş, you live life like you’re a king,” Rosier recalls fondly. “The matchday atmosphere…you feel like you’re important. I didn’t know much about the level in Türkiye, but it wasn’t easy.”
Arrival in Spain and Osasuna
After 126 appearances for Beşiktaş, Rosier returned to france with OGC Nice on loan in January 2024, making only three appearances before transferring to newly promoted LaLiga side Leganés on a free transfer. He made his Spanish debut on August 17, 2024, against Osasuna, showcasing his defensive prowess with four tackles, six clearances, and two interceptions in a 1-1 draw.
Despite Leganés’ eventual relegation, Rosier proved to be an invaluable asset, leading the team in interceptions (1.6) and tackles (2.2) per game.His performances attracted interest from clubs like Fulham and Eintracht Frankfurt, but he ultimately chose to join Osasuna on a free transfer, signing a three-year contract.
“Osasuna wanted me a lot, and that is important to me,” Rosier explained. “I love LaLiga and playing in Spain. I felt a family atmosphere at Osasuna, and we had a good understanding during talks.”

Looking Ahead with Osasuna
Rosier has seamlessly integrated into osasuna’s squad, participating in all six preseason friendlies. With the departure of Jesús Areso and Rubén Peña, he is expected to secure a starting position on the right side of defense under new manager Alessio Lisci.
“Lisci doesn’t just think about possession, but also defense,” Rosier noted. “He wants me to play higher up the pitch and has made me pleasant with the tactics. we’ll have to see what happens against Real Madrid, but I think we can produce a good season.”
Pro Tip: Rosier’s versatility allows him to play on either flank, providing tactical versatility for Osasuna.
Having conceded three goals in each of his previous three encounters with Real madrid, Rosier is determined to turn the tide and inspire Osasuna to their first victory against Los Blancos since January 30, 2011. He acknowledges the long season ahead but believes Osasuna can challenge for European qualification.
“last season,Osasuna finished ninth and were a goal away from qualifying for Europe,so it’s normal to start thinking about it. I think the team has to be aiming to finish fifth,sixth,or seventh and qualifying for Europe – we can do it.”
as he enters his 29th year, Rosier is focused on maintaining his fitness and continuing to refine his game. He aims to establish himself as a key player for Osasuna and contribute to the club’s success in LaLiga.
“Osasuna fans want a player who will fight for the club and play with their heart,” Rosier concluded.”I’m not the best, but I play with my heart. I fight for every single game, and I think I will provide something a little different with my style on the pitch.”
The Evolution of the Fullback Role
The role of the fullback has dramatically evolved in modern football. Once primarily defensive, fullbacks are now expected to contribute significantly to the attack, providing width, delivering crosses, and even scoring goals. This shift requires a unique blend of athleticism, technical skill, and tactical awareness. Players like Valentin Rosier exemplify this modern fullback,combining defensive solidity with attacking impetus. Research by Hughes & Franks (2005) highlights the increasing demands placed on fullbacks in the Premier League, emphasizing the need for high levels of endurance and tactical flexibility.
