World Cup 2015: Buttler backs 'lethargic' England squad to revive 'struggling' CWC campaign

England wicketkeeper-batsman Jos Buttler has backed his team to stage a strong comeback in order to revive their struggling World Cup campaign, stating that the team has got to win both their upcoming matches to ensure a quarterfinal berth.

The Eoin Morgan-led side is currently fifth in Pool A table, and must defeat Bangladesh in Adelaide on Monday and minnows Afghanistan in Sydney on March 13 for securing a chance of quarter-final berth.

Buttler, who is also vice-captain to Eoin Morgan, said that they were confident about themselves and back the quality they have, adding that they have got to play better than they have so far to get through to the quarter-finals, Sport24 reported.

However, Morgan's men might find themselves in trouble if Bangladesh pulls off an upset against co-hosts New Zealand in Hamilton on March 13, as the Asian team has five points to England's two.
