Being the second most successful team with three Asia Cup titles, Pakistan will go into the tournament as one of the favourites along side world no.6 India and South Korea, who have won the coveted tournament four times.
"We have already qualified for next year's World Cup in India, but our main focus will be on performing well in the Hero Asia Cup," said Khan, who has recalled some experienced players in the national camp.
"We will need to make improvement in all areas of our game if we want to achieve our goal this time. We have faced a tough time in recent years as we failed to qualify for the last World Cup, and then 2016 Olympic Games, therefore we want to deliver our best starting from Hero Asia Cup 2017," he added.
