Newcastle United have made fresh enquiries for Zenit St Petersburg's prolific striker Sardar Azmoun.
The 27-year-old Iranian international is out of contract in the summer and has been in talks over a move to Lyon.
However, despite outlining terms over a four and a half year contract, the French side were unwilling to pay more than £3m to sign him this month.
That has left the door ajar for Newcastle who are looking for cover while Callum Wilson recuperates from a calf injury.
Azmoun has scored 11 times this season and impressed with goals in the Champions League against Chelsea and Juventus.
