General director
On 3 September 2012, Hulk completed a transfer of €60 million, with Porto receiving €40 million, to Russian Premier League club FC Zenit Saint Petersburg, reuniting with former Porto teammate Bruno Alves. This transfer fee caused a lot of debate and a great stir since Mitrofanov, General director from Zenit denied publicly. Russian media R-Sport even claimed that Mitrofanov had shown the media the sales contract and the fee on the contract was €40 million and not €60 million. However, Porto also confirmed in its unaudited quarterly report in Q1 2012–13 that the club did not pay for third parties ownership (15%), agent fee nor solidarity contribution (5%), which all normally included in the transfer fee, as in the case of Radamel Falcao.
