Arsenal must increase their opening offer of £60 million for Moses Caicedo of Brighton.
The Ecuador midfielder is a huge target for the Gunners before the transfer window closes.
However, the Evening Standard and other sources state that an initial bid has already been turned down by Brighton.
The Albion are not interested in parting with a key player midway through the season.
Unless they get a mammoth offer that is almost double the initial offer, they are not going to consider a sale.
Brighton recently sold Leandro Trossard to Arsenal for £26 million, but only because the player was out of favor at the club.
