He was speaking to BBC Sinhala Service ahead of Sri Lanka’s crucial encounter in the tournament against Pakistan.
The winner will qualify for the semis, with India, Bangladesh and the hosts already among the last four.
South Africa, Australia and New Zealand have failed to qualify and Asian teams have played well in the fast and moving pitches in England, he noted.
In today’s game, Sri Lanka will be at an advantage against Pakistan which is without the services of Misbah ul-Haq and Unis Khan, said Herath.
Also, Sri Lanka’s young players have had a morale booster from the win against India, he said.
Asked if Sri Lankan players are having a fitness problem, as they are regularly prone to injuries, he said he could not say so.
Injuries are unavoidable, but it is good if anything could be done to prevent them, he said.
Sri Lanka lost Kusal Janith Perera and Chamara Kapugedara in the tournament due to injury, while captain Anjelo Mathews did not play in the first game.
During the 2015 World Cup too, several Sri Lankan players sustained injuries.
