Bayer Leverkusen have reportedly launched a £9m bid for Arsenal defender Sead Kolasinac.

The Gunners are expected to be active before the end of this summer's transfer window but will need to raise funds through player sales in order to improve their squad in the coming days.

According to the Daily Mail, Leverkusen have offered £9m for Kolasinac and are hoping to soon secure a deal for the 27-year-old, having seen talks progress on Wednesday.

The Bosnia-Herzegovina international joined the Gunners from Schalke 04 in 2017 and has made 107 appearances for the Premier League side in all competitions.

Kolasinac has featured on three times for Mikel Arteta's side this term but has been an unused substitute in two of their three Premier League matches in 2020-21.

The defender's existing deal at the Emirates Stadium is due to run until June 2022.
