- Sri Lanka is the oldest team in the tournament and Afghanistan is the youngest based on the teams' average age.
Chris Gayle , the dazzler from West Indies, will play his fifth and final World Cup, one short of legends like Sachin Tendulkar and Javed Miandad.- The five youngest players playing the tournament this year are from Afghanistan and Pakistan.
In the tournament starting tomorrow (May 30), this format would amount to 9 one-day international (ODI) matches for every team before the semi-final stage. Compare this to the 2015 world cup where only the finalists played 9 full matches after surviving two knockout rounds.
A team of veterans may be able to handle pressure situations better, but could be found wanting due to the high number of league matches. While a youthful team may show sparks of brilliance and stamina but may not be able to finish the game.
There is also the possibility that age may not be a determinant in how a team progresses - considering the increased emphasis on fitness. These probabilities and how they pan out is what makes the World Cup so exciting.
An analysis of the average age of the World Cup squads reveals that debutantes Afghanistan have the youngest squad. Sri Lanka, with an average age of 30.40, has the oldest team in the competition. The Indian squad is among the older ones in the competition.

The Veteran
The West Indian Chris Gayle is the only player in the current squads to have played in the 2003 World Cup. Since this is Gayle’s fifth and final World Cup (he has announced that he will retire after its conclusion), he will not be able to catch up with Sachin Tendulkar and Javed Miandad, who have played 6 World Cups.
Oldest player
Imran Tahir is the oldest player in the World Cup. Tahir was 32 when he made his one-day international debut against West Indies in the group-phase of the 2011 World Cup; he had a good outing, taking 4 wickets for 41 runs. Since then, the Pakistan-born spinner has established himself in South Africa’s limited over squads.
