Juventus president Giovanni Cobolli Gigli admits their summer market plans are stalling because some players do not want to leave.
He said: "Our market is blocked by players who don't want to be sold. Sure, before we can buy we have to sell.
“(Christian) Poulsen is one of the players we put up for sale and in theory also David Trezeguet.
“It's clear we have to accelerate. It would be very positive if we could communicate our sales and subsequent acquisitions within the next 10 days,” he explained.
