I agree with those that say VDV isn't lazy. He does work hard throughout a match (although he is not our hardest working player despite how much a certain poster will try and pass that off as fact!), and he does cover a lot of distance mainly because he drops deep from his forward position on a regular basis. And covering distance during a match isn't the same as working hard. Constantly jogging around the pitch without ever really pushing yourself to high intensity will get you a lot of distance covered during 90 mins for example. (but I repeat, I do think VDV does work hard).
However, from what I have seen of AVB at Chelsea I don't think VDV has much of a long term future and here is why:
1) AVB likes fast players. VDV may work hard, but he is slow and not very agile.
2) VDV can't play central midfield in the Premiership on a regular basis to good effect. The game is too fast there. If he did play there he'd have to play the "Lampard" role and we all remember Lampard (despite scoring goals) was dropped. One of the big reasons Lampard was apparently dropped was because he was too slow. VDV also can't play central midfield because defensively he is very poor.
3) VDV loves to roam. AVB's Chelsea side were very rigid, and players who stepped outside of the tactical game plan were dropped for defying the Manager. AVB is a tactical Manager who has a game plan and for it to work it's imperitive players follow it.
4) VDV is a fiery so and so. AVB doesn't like fiery players, and will bench them, stick them in the reserves and/or sell them at first opportunity the first time they cross him.
5) The best role for VDV in AVB's system would appear to be right inside forward, but again I can't see AVB utilising him there due to lack of pace.
6) Squad rotation, AVB loves it. Will VDV be happy sitting on the bench? No, he'll want to leave.
I'd be surprised if VDV leaves this Summer, but I wouldn't be at all shocked if he was gone in January.
