5 reasons why Sri Lanka has been struggling in ODIs 

#1 Angelo Mathews's prolonged troubles

Angelo Mathews

Ever since he first arrived on the scene, Angelo Mathews looked like one of Sri Lanka's best players and one of the world's premiere all-rounders. Following the retirements of some stalwarts, Mathews became Sri Lanka's best batsman and, for a while, was counted among the best batsmen in the world. He was also a very good bowler.

However, persistent injuries forced him to give up bowling, and a prolonged loss of form as a batsman further weighed him down. He played the ICC Champions Trophy earlier this year solely as a batsman, and Sri Lanka missed out on his formidable talents as a bowler.

His loss of batting form and long absences from ODIs have been major factors in Sri Lanka's ODI troubles.
