Spurs had looked set to clinch a £6.9 million deal for the highly-rated centre-back, but were reportedly unwilling to wait for Steaua to complete the deal after their Champions League qualifier against Dinamo Tbilisi, with the second leg set to take place on August 6.
"Who are Tottenham?! Do not do any transfer, my name is Gigi Becali, I'm not a slave to anybody! We have an important game in the Champions League, why can't they wait?" Stoica relayed to DigiSport.
"Until winter he will not leave under any circumstances. This could be a blow to Chiriches, but he should understand," Stoica added. "He owes a lot to Steaua. Things are good, we are in qualifying for the Champions League. We are in good shape."
"[Tottenham] made a big mistake. They sparked anger in Gigi."
Earlier on Wednesday, Spurs sold 21-year-old centre-back Steven Caulker to Cardiff City.
