Truffert, a left-back who joined the team from Rennes in the summer, has settled in well.
Iraola notes that Truffert's experience and language skills have made his transition easier.
At 23, Truffert has played a significant number of games for his previous team and even served as captain.
This experience, combined with his proficiency in English, has given him a head start in adapting to the new team.
Iraola is happy to have a player with Truffert's qualities, which are not easily found in potential recruits.
Truffert has made a strong impression in his early games, but Iraola emphasizes that he wants to see consistent performance throughout the season.
