If anyone wonders how Robin Van Persie got "easily" the job of manager at Feyenoord, that dude was always there all his life. I mean sure he was transferred to other teams at times, but he was raised there as a kid, played there at the main team as an adult, and he always goes back there, after his playing career was over, he literally just sent there and got his licenses and started training with the youth team and all, basically earning his managerial debut in another team but until then spent time as coach in many stages of Feyenoord as well.
This is why I honestly can see why Feyenoord ended up getting him, this dude basically spent 20+ years there in total, who knows the team better than him? If he is a good manager, he should shine here even more.
