Instead, in his first squad of the new season, Capello has called up Manchester United's 20-year-old striker Danny Welbeck and uncapped Tottenham right-back Kyle Walker, 21, two of the new generation of players he is likely to entrust with responsibility at Euro 2012 if they impress this season.
As Capello sets out his stall for his last ten months in charge of England, which start with Wednesday night's friendly against Holland at Wembley, there is a hint of what is to come as well as a definitive statement on what will never come to pass.
Loose cannon: Capello has voiced his concerns over Barton
Barton, who Newcastle said they would release on a free last week after his persistent criticisms of the club's owner on the social networking site Twitter, had delighted some by quoting George Orwell and George Washington while championing his right to free speech.
He even said he needed to get in touch with Isambard Kingdom Brunel when it was suggested that some bridge-building with Newcastle might be in order to restore the relationship. On Saturday he changed his profile picture to one of Che Guevara.
Capello, though, believes the Newcastle player, who won one England cap under Steve McClaren in 2007, is too 'dangerous' to be considered for England - not for his verbosity but because of aggression.
'I think he is a good player,' said Capello. 'But he is a dangerous player because sometimes on the pitch you can play ten versus 11. He might get sent off. He's a good player, but the problem is sometimes on the pitch.
'This is not a good moment to decide something about him. When a player is fighting with his club it is normal to stay outside (England's squad). The relationship between a club and a player is really important.'
Play time: Fabio Capello will have more serious matters on Wednesday
Capello will stick by Scott Parker - and in all likelihood start with him in midfield against the Dutch, given that Jack Wilshere is expected to be withdrawn from the squad.
Even though West Ham's Parker is currently performing in the Championship, the England manager insists that last season's Footballer of the Year still has a future with England, though it is clearly preferable that he plays in the Premier League.
'I will go to West Ham to see the games and check everything,' said Capello. 'It is important for him to play in the Premier League. I know he is really serious. He is a focused guy.
'It is no problem but they play more games than the Premier League. He is one of the players who can play with the national team. He is part of the group. If he is fit, he will be OK and stay with us.
'If I find a really good player in the Championship I will pick him. Why not? You know him (Parker) well. (But) I hope for him and for me he will play in the Premier League.'
Rising star: Danny Welbeck
Though Capello will select his strongest available side for this friendly, with Euro 2012 qualifiers against Bulgaria and Wales less than a month away, the selection of Welbeck and Walker indicates that the Italian is developing a nucleus of young players who will be considered for a fast track promotion to the squad for Euro 2012.
Welbeck, who made his debut against Ghana in March, replaces Darren Bent, who was withdrawn by Aston Villa with a muscle strain. Walker and Micah Richards have displaced Glen Johnson, who injured a thigh in Liverpool's 2-0 win over Valencia at Anfield on Saturday.
Others are likely to be given their chance soon. Manchester United's ?18million signing Phil Jones impressed during an otherwise disappointing Euro Under-21 tournament in Denmark.
Liverpool right back Martin Kelly and midfielder Jordan Henderson will also be monitored with a view to promoting them next summer.
'Jones, Henderson, Kelly - the right-back when Glen Johnson was injured - he was interesting,' added Capello. 'I think now the new generation is good. I hope they will be OK in a short time.'
What Capello hopes is one or more will make an impact similar to that of Wilshere last season, though he concedes the emergence of the teenager was extraordinary.
'It is not easy to find a player like Wilshere who explodes in six months. This is the big difference. He is an extra player, here (in the head) and on the pitch. He is a leader. It is really difficult to find this.'
For now, though, it will be as many of the golden oldies as Capello can muster on Wednesday. The future, however, remains in the hands of the likes of Walker and Welbeck. And that future could come as soon as next summer if they impress.
