Month by month review
June
Due to the financial problems, the club had to terminate or not extend the contracts of seventeen players, including Pablo de Lucas, Victoraș Astafei and Jean Sony Alcénat. On 3 June, Tibor Selymes became the head coach of "The Oilmen". On the 11th, the club's reorganisation plan was voted, therefore bankruptcy was avoided for the time being. Nike remained the kit manufacturer, while Superbet, a gambling company, replaced Alexandrion as the main sponsor of the team. "The Yellow Wolves" settled their pre-season training stage at Zlatibor, in the neighbouring country Serbia. The stage started on June 21 and ended on July 4. The club tested and signed new footballers during this period, generally ones who played in the French lower divisions, like Abdellah Zoubir, Ismail Hassan or Nicolas Farina. Ex-Dynamo Moscow midfielder Adrian Ropotan returned to Romania, six years after he left Dinamo București. Petrolul also convinced Brazilian goalkeeper Peterson Peçanha to extend his contract.
July
On 11 July, Petrolul played its first official game of the season against Steaua București, in the Liga I. The match ended goalless.
