Cagliari have rejected a deadline day sale of Radja Nainggolan to Juventus.
The club's general manager Francesco Marroccu has warned Juve a summer move may also not happen.
"The President has a pact of honour with Marotta and Juventus, but there is no final agreement, nothing set for definite, before June so many things can change.
"The goal of Cellino was to retain Nainggolan at Cagliari. Juventus were entirely proper with us, you must give credit to the Bianconeri's management.""Nainggolan has never expressed a desire to leave," he told TuttoCagliari.net.
