Its a bit of both I think, Wenger absolutely retardedly seems to think replacing him next year with no money will be a better option than replacing him this year, with an extra 20mil.
Nasri wants money and staying an extra season probably means higher wages and bigger signing on bonus, ok, he'll lose part of the supposedly 3mil increase we were going to give him, but considering he's being supposedly offered 2-3 mil above that from City anyway what does he care.
Like I said, if he was refusing a 80k a week deal and we could only get 5mil for him, but 20mil for one of our worst performers in preseason, its a freaking steal for us.
