Agent Dennis Lachter has invited Barcelona to make a formal bid for Arsenal star Andrey Arshavin.
Arshavin, 28, has enjoyed a hugely successful start to his career at Emirates Stadium but there have been rumours linking him with a summer move to Camp Nou.
And Lachter, who represented Arshavin when he made his move from Zenit St Petersburg in January, has now called on the European champions to make a move.
"Before anything else, Barcelona should make a formal offer," Lachter told COM Radio.
"Then we can sit down and speak."
However, it remains unclear whether Lachter is still working as Arshavin's agent as the player claimed last month that he no longer required his services.
"Recently, I sent a formal letter to Dennis Lachter, which said that I do not want him to continue to represent me and that I will act on my own behalf," he said in the Daily Mail.
