No way we'd lose Vincelot, hugely valuable player. As for the other two, maybe they are being re-assigned numbers? Hoskins is unlikely to be sold after being injured. Sparrow is the only one that could go IMO.
I think we could see Vicente on the wing playing a free role with Bridcutt and crofts in the middle and barnes playing behind the striker from deep with another winger and CMS or another striker.
