Newcastle United target Lucas Perez has handed in a transfer request at Arsenal.
The striker is keen to leave the Emirates Stadium this summer after a season of frustration last term, with Gunners boss Arsene Wenger preferring other options.
Wenger is willing to sell and has slapped an asking price of €15m on Perez's head, amid interest from Newcastle, Deportivo La Coruna, Sevilla and clubs in Germany and Turkey.
Now, according to Spanish radio station COPE, Perez has officially notified Arsenal of his desire to leave.
The striker may also hope it pushes Arsenal to consider lowering their asking price for him.
Perez's former club Deportivo La Coruna have already put in a bid of €9m to re-sign their former goalscorer.
