The reigning Russian champion still managed to make a big splash in the market before the window closed by completing an 100 million euro combined double signing of Porto forward Hulk and Benfica midfielder Axel Witsel.
However, it has since emerged that they also tried to make another double swoop altogether, with the Portuguese pair of Nani and Joao Moutinho pursued if the aforementioned move failed to materialize.
"We really have been negotiating Nani and Moutinho, but Hulk and Witzel were top priorities," explained Zenit chief Maxim Mitrofanov.
"It must be understood that any transfer campaign is based on the list of players, ranked by priority."
Mitrofanov also stated that a move was possible for the Manchester United man until they spoke to the player and realised that his salary expectations were beyond even their resources.
"If Hulk had demanded 8m-10m euros a year, these conditions would have been unacceptable for Zenit," Mitrofanov explained.
"The transfer of Nani failed mostly due to this reason, as he asked for an enormous salary and we would not pay him."
Nani has just two years remaining on his contract at Old Trafford, while Moutinho was reportedly just minutes away from completing a switch to Andre Villas-Boas' Tottenham Hotspur before the window closed.Follow GOAL.COM USA on
