Bruce Rioch feels Arsenal should get tougher with their players.
The former manager believes Arsenal must look at the way Manchester United do business - toughen up, rediscover their competitive edge and hark back to the days when Patrick Vieira and Co took no prisoners.
"I've got a lot of affection for Arsenal, there's no room in my life for bitterness. It is a great club by any yardstick," says Rioch, now living in Cornwall, to the Mirror.
"Yes, United scored some great goals but losing two outstanding players like Fabregas and Nasri is really going to dent any team's confidence - unless you've got like-for-like quality as immediate replacements.
"Their moves turned into long-running sagas when something should have been sorted out quickly.
"United sent out a message to the rest of the world - we are not a club which sells our best players.
"Bill Shankly once told me that when a player got towards the end of his contract at Liverpool, he would be offered a new deal. Any hesitation and he was history. Shanks took it as an indication his head was elsewhere.
"I feel Arsenal should have done that with Nasri."
