Arsenal could reportedly have to fork out £63million if they wish to make a bid for Bayer Leverkusen winger Moussa Diaby.
The Gunners are looking to strengthen their side, which will need some bulking if they qualify for next season's Champions League.
Diaby is a player who has attracted the attention of many clubs this season thanks to his stellar performances for Leverkusen.
German publication Sport Bild have reported that the Bundesliga side would command a fee of at least €75 million (£63m) for any club who look to snap him up during the summer transfer window.
