There is daily contact, be that between Vitesse technical chief Mohammed Allach and Michael Emenalo or Bosz and Eddie Newton, the coach responsible for monitoring Chelsea's army of players on loan, or chief executive Joost De Wit and influential Chelsea director Marina Granovskaia.
"They don't put pressure on us or ask us to do things we don't like, not at all, I mean that," Bosz told the Daily Mail. He was appointed last year after a meeting in London with Emenalo and Granovskaia.
'They explained how they worked and what they expected. I tell them positions where I'm looking for players, they tell me what they can do for us and we look at whether it's possible.
"Once we agree for a player to come to us, I have to develop him and in the end we hope they are good enough for Chelsea. They are not saying I have to play them, or I have to play this kind of way. I'm the coach and I decide. But of course we work together."
