Besiktas made an offer for Trossard: how Arsenal will respond to the transfer attack.

According to The Sun: Arsenal received an unexpected offer for Leandro Trossard just three days after the summer transfer window closed in the UK, sources report.

Although the Gunners can no longer sign new players, they still have the option to sell players to clubs that can make transfers, such as in Turkey.

This unexpected offer came from Besiktas, who have shown interest in the 30-year-old Trossard.

According to the Turkish publication Sozcu Spor, the Istanbul club has already made a bid of £19.1 million for the winger.

However, the North Londoners have not yet given any response to Besiktas' offer.

Sergen Yalcin's team still has some time, as the transfer window in Turkey closes only on September 12.

This comes after Trossard signed an unusual new contract with Arsenal this summer.

The Belgian player received a pay increase, but the term of his contract remained until 2027.

The former Brighton player received offers from Brentford, Aston Villa, and other clubs during the summer.

According to SunSport, Besiktas also considered the possibility of signing Jadon Sancho, who became a free agent after Manchester United and is now looking for a new left winger.

This news comes after Sancho chose Aston Villa, which he joined on loan on the last day of the transfer window.

Villa will cover 80% of the winger's weekly salary of £200,000.

The potential transfer of Trossard to Besiktas highlights the active transfer policy of the Turkish club, which is trying to strengthen the squad at the start of the season. For Arsenal, this also indicates the demand for talented players, despite the fact that the transfer window in their league is already closed.

It is expected that the coming days will be crucial as Arsenal must make a decision regarding Trossard's future in light of the interest from the Istanbul club.
