In an interview with AD, Hartman spoke about his broken relationship with Van Persie. He stated: "I'm very honest about that. I've had a really bad feeling in Rotterdam these past two months. I was walking around the club with a bad feeling. That wasn't the fault of the fans, from whom I still receive messages. But it was the problems with the manager. I think everyone was more or less aware of that.
"He never expressed it outright; it's just a feeling. But he said in a conversation: 'We really want you to stay. I really want you to stay. You're an important player for me.' I told him I wanted to think about it after my injury. That I was just happy to be able to play again. In the weeks that followed, because I didn't want to re-sign, there was suddenly a different bond. I got the feeling he looked at me differently. You see exactly the same thing now with Quinten Timber, whose captaincy was stripped from him. I think that's a shame, because in my fifteen years at Feyenoord, I never had a problem with anyone. Especially the manager, such an important person."
Zerrouki told Voetbal International: "Well, what can we say? In the beginning, he was very involved with me. I started to enjoy it again, but in the last week of last season, something changed. That's how it goes in football sometimes. Let's just say I didn't do anything wrong. The bond simply weakened in the final week of the season. It wasn't necessarily football-related. He had an opinion about me, and I didn't agree with it. From that, I concluded I'd be better off playing elsewhere."
