Speaking with Wiwsport, Diouf explained: "He is not a player we are going to talk about for the January transfer market, called the 'repair transfer window '.
"This is for teams who are in trouble or who need a rookie to replace an injured player. And Sadio Mané played the first phase of the Champions League with Liverpool. This transfer window is not made for players playing in big clubs.
"If we want to talk about Sadio Mané, it is from May that work will start, with meetings in hotels or bars. Before this period, it will be private discussions between, for example, Zidane with intermediaries. The press can use this leaked information from private exchanges and make headlines.
"The feasibility of transfers begins to materialise around May, June."
