Perth: Question marks have been raised about their ability to trouble batsmen in overseas conditions but 'spin twins' Ravindra Jadeja and Ravichandran Ashwin has 'proved their critics wrong' with an impressive start to their World Cup campaign, feels team's premier batsman Virat Kohli.

With convincing wins over Pakistan and South Africa in the first two games, no one can deny the role played by off-spinner Ashwin and left-arm spinner Jadeja. Between them, they have taken six wickets (4 for Ashwin and 2 for Jadeja), having collectively given away only 175 runs in 36.2 overs at an economy rate of less than five runs per over (4.83).
