Emirates club want double from the Nou Camp.
Arsenal have rejected a £30million bid for midfielder Cesc Fabregas from Barcelona and have demanded double that amount from the Catalan giants.
The Spanish and European champions made the verbal offer this week but it was quickly dismissed by the Gunners board.
The Nou Camp side had wanted to make a cash-plus-player deal but Arsenal are only interested in money.
Gunners boss Arsene Wenger has been adamant his skipper will not go but the club realise they can only hang on to the midfielder for so long.
“There was an offer and it has been turned down flat,” an Arsenal source told the Daily Star.
“They have been told to come back when they are serious with a proper offer and we will consider it.”
Pep Guardiola has made the 24-year-old his main summer target and has chased him since last summer.
Barca are considering upping their offer to £35m, but it is still unlikely to be enough for Arsenal to sell.
The Gunners demanded £60million for their talisman but it is likely they will accept a bid around the £45million mark.
The La Liga side want the deal wrapped up by July 4 but are so confident of landing Fab they have no list of alternative candidates.
Guardiola said: “The priority is Cesc because he is part of our new project. We can’t afford to stand still. But there is only so much money available.”
