The striker was a huge success at the Stadio Santâ€™Elia before he left to join Inter in an injury-ravaged spell.
He had announced his return to Sardinia, but something changed for the 31-year-old Honduran.
â€śSuazo hasnâ€™t signed the contract we proposed,â€ť President Cellino told Unione Sarda newspaper.
â€śI donâ€™t think it was just his decision, as evidently he was given bad advice. So, if David has any recriminations, he can talk to other people, but not to me.
â€śLetâ€™s be clear, if Suazo had been a player in perfect health, I never wouldâ€™ve brought him back, because I tend not to try again with those who have left Cagliari.
â€śSeeing as he was coming off a difficult year affected by a serious injury, in recognition of all he had done for us in the past, I thought weâ€™d give him a chance to get back to playing football.
â€śI offered a contract, which in my view was perfectly dignified, and he seemed happy. After a few days, he said he was unsatisfied and would not sign it.
â€śI can only deduce someone changed his mind. At this point, I am offended and as far as Iâ€™m concerned the issue is over.â€ť
