5 reasons why Sri Lanka has been struggling in ODIs 

#4 Declining powers of Malinga

Lasith Malinga

For a large part of his career, Lasith Malinga was one of the world's best limited-overs fast bowlers, and his ten overs were often the key to Sri Lanka winning matches.

It was as a death over bowler that he was most feared, and his overs have swung many games for Sri Lanka over the past decade.

However, he is not the same bowler anymore. His pace has declined, and plenty of batsmen seemed to have worked out how to play him. Malinga's decline has been directly responsible for the huge scores that Sri Lanka concedes these days. In addition to that, he doesn't play often enough.
