Newcastle are expected to be in the market for a new striker in the January transfer window, with both Joselu and Dwight Gayle struggling for goals this season.
The Magpies were one of a number of clubs linked with a move for Besiktas forward Tosun, who is expected to leave Turkey at the start of 2018.
It is understood that the Premier League side remain firmly in the race, but according to Sporx, Bundesliga outfit Wolfsburg are attempting to beat Newcastle to the 26-year-old’s signature after making a £9m bid.
The report claims that Wolfsburg approached Besiktas earlier this week, and are hopeful of reaching an agreement ahead of the January transfer window.
Tosun joined Besiktas from Gaziantepspor in 2014, and has scored more than 50 times in all competitions for the Turkish giants over the last three years.
This term, the forward has managed three goals in eight league appearances, whilst he has also struck three times in the group stage of the Champions League.
A Turkish international of 24 caps, Tosun is said to be on the radar of a number of European clubs ahead of the opening of the winter window at the start of 2018.
The striker’s 20 league goals last season helped fire Besiktas to the Turkish title, and at the age of 26, Tosun certainly has time to improve.
Crystal Palace have also been credited with an interest, and it seems that the Eagles and indeed Newcastle will need to move fast in order to prevent Wolfsburg from securing a deal for one of Europe’s in-form centre-forwards.
