Former Australia opener Matthew Hayden feels Ravichandran Ashwin's stats are "simply phenomenal" but Harbhajan Singh in his prime had to shoulder more responsibility since he did not have the fast bowling support which Ashwin gets. Ashwin recently broke Dennis Lillee's record to become the fastest bowler to 300 wickets in 54 Test matches. Hayden had faced Harbhajan in his prime and also watched young Ashwin from close quarters during his days with Chennai Super Kings.
