The Three Lions recorded their worst ever showing at the tournament since 1958, and the former Man United man feels his ex-team-mate won't be happy with his performances
Roy Keane says Wayne Rooney will know he "should've done better" at the World Cup but predicted his England career still has plenty of twists and turns to come.
The Manchester United striker hadn’t scored in the competition in his two previous attempts in 2006 and 2010 but at last broke his duck with a goal in the 2-1 defeat to Uruguay.
That result saw England knocked out of the tournament at the group stage as they failed to win a single game in Group D, and Keane believes he will be quick to criticise himself.
"If you think Wayne Rooney's gone, then you are sadly mistaken," the former Manchester United midfielder said.
"I thought he did OK. I'm sure he will feel that he should have done better. Top players are quick to look at themselves."
The Republic of Ireland and Aston Villa assistant manager also pointed to a startling lack of experience within the squad as the major reason behind another disappointment for the Three Lions.
"I said England would struggle but that's not football knowledge, that's just common sense," Keane added.
"If you look at the squad, they should have done enough to get out of the group. The players didn't perform.
"[Republic of Ireland] played Costa Rica last month and if you had told me then they would top the group I'd have said you were mad.
"But if I look at the England squad and the players then a lot of them still lack vital experience. Whether it's Champions League experience or big-game experience.
"A lot of those players are yet to win a trophy and yet people still expect them to go to the World Cup and reach the quarters or semi-finals.
"People are ranting and raving about the younger players – they still have a lot to do. We can argue all day about winter breaks and all the rest of it, but the fact is they should have done better."
