Barca feel they're the aggrieved party in the controversial transfer, despite their public touting to Cesc.
A Barcelona source told The Sun: "It's true the negotiations have been fraught and full of recriminations.
"Arsenal keep complaining, they say we are trying to sign Cesc on the cheap and keep asking for more cash.
"But we feel we have far more reason to feel aggrieved.
"The reason we won't pay any more is because so many of our youngsters have been ghosted away on the cheap by Arsene Wenger - after years of being developed and trained by us at great expense."
