Arsenal have reportedly turned down a third bid from Crystal Palace for out-of-contract striker Eddie Nketiah.
Nketiah, 22, is set to become a free agent in the summer with his current Gunners deal up at the end of June.
The north London club are keen to tie their academy graduate down to an extension, but he rejected their latest offer last month.
As a result, he became eligible to sign a pre-contract agreement with a foreign club at the turn of the year, with Bayer Leverkusen understood to be circling.
