Lack of Consistency
Sri Lanka cricket for example has not been constant for a number of years now. In this situation, the team demonstrates an irregular dynamics of a talented but unstable performance. The top order of Sri Lanka in a 3rd ODI against India includes Pathum Nissanka, Kusal Perera, and Charith Asalanka, none of the players managed to convert their promising starts into a big score and thus, there was a failure of the middle order.
Poor Leadership
Sri Lanka has comprised of bad leadership either on the field or off the field. Sri Lanka Captain Charith Asalanka has been on the e receiving end concerning his strategies especially in the 3rd T20I where he opted for short and wide, giving Indian batsmen a bouncer-free feast.
Lack of Talent Development
Cricket is very popular in Sri Lanka and there is a vast talent base, but there has been a conductive failure to properly groom and boost the youth talent. Youngsters such as Chamindu Wickramasinghe and Maatesha Pathirana have quite often performed well, although they have not had adequate exposure.
Over-Reliance on Senior Players
Sri Lanka has depended too much on senior players such as Ramesh Mendis who is in a very poor form at the moment and Wanindu Hasaranga, whose bowling has been very volatile.
Lack of Adaptability
During this particular period the Sri Lankan team had not been able to manoeuvre well to the different conditions and opposition. The examples can be pointed to the match of the 3rd T20I when the team could not deal with the dewy surface and subsequently, India chased a small total with relative comfort.
