Speaking to ITV after the Gunners embarrassing2-1 defeat at the hands of Swedish side Östersunds FK in their UEFA Europa League last-32 fixture, Keane launched a scathing attack on the England worldwide.
The morning after the return leg defeat to Ostersund, the Arsenal manager conceded that Wilshere, who was named captain for the match, did not have his best game at the Emirates but insisted that Keane should know that no player is capable of delivering flawless performances all the time.
Keane had weighed in on Arsenal's drab display in their defeat, picking out Wilshere as the starting point for their troubles.
Keane then took aim at Jack Wilshere, Arsenal's captain on the night.
The Arsenal boss said of the 26-year-old midfielder: "That decision doesn't depend only on me".
'The manager summed it up. "You're looking for your senior players to lead by example".
"Probably the most overrated player on the planet."".
"It was not his best performance but Roy Keane knows that can happen to everybody".
"If you start the game slowly no matter how good you are it's hard to get going". It's not like a light switch, you can't just turn it on and off.
Manchester United legend Roy Keane has stuck the boot into Arsenal following a shambolic performance at home to Ostersunds.
Less than 12 hours had passed since Roy Keane's scathing criticism of Jack Wilshere when Arsene Wenger responded.
It was certainly not one of Wilshere's best performances in an Arsenal shirt as Arsenal suffered one of the worst results in their history just a few days before they meet Man City in the league cup final on Sunday.
