Russian media claim Lassana Diarra abandoned a Lokomotiv Moscow training session to push through a Napoli move.
The former Chelsea and Arsenal midfielder has been linked with the Partenopei this summer.
According to The Moscow Post, Diarra refused to attend pre-season training with Coach Leonid Kuciuc.
The French midfielder is determined to leave Russia and force Napoli’s hand in negotiations.
Still 29 years old, Diarra moved from Real Madrid to Anzhi in 2012, then on to Lokomotiv Moscow in 2013.
