According to VoetbalPrimeur, Bosz shared an anecdote about Lang helping new team-mate Malik Tillman settle in during his first weeks at PSV. Lang had arranged for Tillman to get a haircut, which brought a smile to the American's face. This kind gesture is a testament to Lang's character, as he was one of the captains of PSV during his time at the club. Lang and Tillman went on to play 36 matches together for PSV before Tillman left for Bayer Leverkusen in the summer of 2025 for a reported 35 million euros.
