It takes expert planning and a full-time job to take care of Michael van Gerwen, Phil Taylor, Gary Anderson and Adrian Lewis away from the oche.
Ahead of the Premier League Darts play-offs on Thursday at 7pm, live on Sky Sports 2 HD, we asked Sky Sports expert Wayne Mardle to lift the lid on the unheralded but vital job of the helper to a darts player.
Who are these little-known folk?
Mardle said: He has a manager called Will, and you very rarely see Michael anywhere without him.
It's a comfort blanket. Michael has reached sports superstardom because he's so good and so recognisable. His little bald head is never going to be mistaken, is he?
He's recognised left, right, and centre so Michael needs someone to say: 'We're just having a meal, can you come back later?'
Not everyone is in the mood to say 'yes' for a photo. Sometimes, you're having trouble parking the car, you can't find the parking machine and there's a group of lads stopping you for an autograph. That's what Will is for.
It just takes a little bit of pressure off and allows Michael to be as good as he can possibly be.
Mardle said: Phil has Bob Glenn, who is more of a right-hand man than a manager. It's easier, if you're driving somewhere, to sleep than do the driving yourself so Phil lets Bob do it.
It's the silly things. If Phil fancies a nice salad somewhere, Bob will find a nice bistro and sort it all out. There's not much to worry about if you have one of these aides.
Phil likes to be somewhere three hours before he plays so, if there's traffic, Bob works that out accordingly.
Bob doesn't care if he's there 10 minutes before the start, but he knows Phil might get agitated if he doesn't get perfect preparation.
Bob has been friends with Phil for a long time, and it's all about trust. You've got to know that your man is in your corner.
Mardle said: He has a manager and people around him but Gary looks after himself. He and his wife Rachel like doing things together as much as they can.
He's more family orientated, but some other people need to be looked after. Lewis, for example, needs someone.
Mardle said: Lewis has Keith Deller looking out for him, not just financially. He's making sure that everything they do runs smoothly.
Keith has known Adrian since he join the PDC in 2003. They just struck up a relationship.
You've got to like someone, then you have to trust them. Unlike Bob and Phil, Adrian has Keith as his manager - very much a professional relationship.
