Wolves' potential deal for Rubin Kazan's Iran striker Sardar Azmoun is off after the clubs failed to agree terms.
It is understood Kazan wanted an obligation to buy in the summer following an initial loan, but Wolves were reluctant to commit to that now. The deal discussed was a £1.75m loan fee, plus £11.4m purchase.
The 24-year-old has been dubbed the 'Iranian Messi' in his homeland and spearheaded Iran's run to the Asian Cup semi-final this month, scoring four goals in six games before they were beaten 3-0 by Japan.
He was also a key figure in their World Cup campaign last year. Iran were knocked out at the group stage but impressed in a tough group that included Spain and Portugal.
They lost 1-0 to Spain, drew 1-1 with Portugal and beat their other group opponents Morocco 1-0.
Azmoun has 28 goals in 45 games for his national side and has been playing club football in Russia since 2013, when he joined Rubin Kazan from Iranian side Sepahan.
After a loan spell at Rostov in 2015-16, he joined on permanent terms the following season before Kazan bought him back.
He has played Champions League football and previously been linked with Liverpool and Borussia Dortmund.
