England???s 15-run loss to Bangladesh on Monday, their fourth defeat in five Pool A matches, consigned them to a third group-stage exit in five tournaments and plenty of flak from pundits.
But former South Africa all-rounder Kallis feels that with the shackles off, Eoin Morgan???s men will be able to express themselves in Sydney and is backing the side to record a convincing victory.
???I think England will play fearless cricket as they have nothing to lose in the last game of their World Cup,??? said Kallis.
???England have got to have a really bad day and Afghanistan have to have their best day ever [for a shock to happen]. They have got too many good players to lose a game like this.???
Kallis, though, has warned England to brace themselves for a grilling from fans when they fly home from the World Cup early having failed to get the better of a Test-playing nation and ???fallen behind??? their rivals.
The 39-year-old agrees with Nasser Hussain that an inquest into England???s failures down under is needed, but does think they have the players available to compete with the globe???s best ODI outfits.
???England will cop a lot of abuse when they come home, just as we [South Africa] did when we didn???t make it through the group on home soil in 2003,??? added Kallis, who made 328 ODI appearances for The Proteas.
???It???s almost like they are playing olden-day one-day cricket as they??are too conservative and not taking too many risks.
???Most of the other top teams??have gone??the other route and??are more aggressive and powerful so England have probably fallen behind a little bit and need to have a sit-down and work things out.
???The talent is there and England certainly have the players to be aggressive, but it???s about getting the right balance and key players in key positions and not worrying about losing.
???Perhaps getting a few more overseas players into their T20 competition could help as it has done in the IPL with young players learning from experience.???
