Newcastle have lodged a €7.5 million [£6.7m] offer for Paris Saint-Germain striker Mevlut Erding, according to radio station RMC.
Erding has been at the French capital side since 2009, when he joined the club from Sochaux, and has been a regular presence at the Parc des Princes.
Newcastle have been credited with an interest in the Turkey international for the past several weeks, and it is believed the Magpies made a formal approach for the player earlier this week.
However, RMC reports that all of PSG's transfer decisions will be put on hold until Leonardo is officially appointed as sporting director, which will reportedly only happen on Wednesday.
Erding, who has a contract with PSG until 2013, will reportedly not turn down a move to Newcastle, who finished 12th in the Premier League last season.
