Sporting Lisbon winger Gelson Martins is keen to join Arsenal this summer, according to reports in Portugal.
The 23-year-old was one of Sportings standout performers last season with 13 goals and 13 assists in 52 appearances.
And Martins displays in Portugals top flight has reportedly led to strong interest from Arsenal.
Last week, A Bola claimed that the Gunners had a €30 million (£26m) bid rejected for Martins.
And on Monday, the same Portuguese newspaper reported that Arsenal have returned to Sporting with a second offer but have stuck with the same €30m bid.
A Bola report that Martins wants to leave Sporting this summer and Arsenal are hopeful that their continued pressure could lead to a deal.
Sporting, however, consider the offer insufficient and have rejected it for a second time.
Several Sporting players are considering cancelling their contracts with the club after they were attacked at the training ground by fans last month.
But its understood that Martins is reluctant to use this option as a way to leave and would prefer Sporting to sell him.
Martins, who is with Portugals squad preparing for their World Cup campaign, has a €60m (£53m) release clause in his contract.
