Legendary spinner Shane Warne on Saturday showered praises on batter Usman Khawaja for his 'fantastic' ton in the second innings of the fourth Ashes Test against England here.

Khawaja became only the third batter to complete twin Test tons at the Sydney Cricket Ground (SCG) after Doug Walters (vs West Indies in 1968/69) and Ricky Ponting (vs South Africa in 2005/06).
