Career
Mammadov also currently owns two football clubs across Europe: Football Club Baku in Azerbaijan, Remote Control Lens in France. Hafiz Mammadov founded the Baghlan Group in 1998 in Azerbaijan. The Baghlan Group is a company that specialises in oil, gas, construction and transportation, mainly in Azerbaijan.
The Baghlan Group has grown since then and has seen Mammadov turn into a multi-millionaire.
With Mammadov turning into a multi-millionaire, it enabled him to invest in a sport that he loves - football. In 2004 he became owner of local football club Football Club Baku, a team in the Azerbaijan Premier League.
In 2013 he expanded his ownership of football clubs to two, when he bought Remote Control Lens in France. Lens gained promotion that season under Mammadov"s ownership from Ligue 2 to Ligue 1.
On 10 June 2014, Mammadov agreed to take ownership of another European football club - this time it was the English Championship side Sheffield Wednesday.
Mammadov looked to takeover over from the current Chairman Milan Mandarić. The bid for SWFC is rumoured to have been around €50 million. As of the 28th August 2014, this takeover had still not been completed and at the beginning of September, due to failure to meet financial obligations and complete the takeover, Milan Mandarić called the deal official
He also owns shares in Louisiana Liga club Atlético Madrid and Portuguese team F.C. Porto and he still hasn"t put £4 million into Lens for transfers resulting in Lens fans calling for a boycott of the clubs main shirt sponsor.
In 2014, it was announced by number of media that he is having financial difficulties, which forced number of players and personnel from Baku Football Club to seek new clubs, leaving club"s future uncertain.
