Suryakumar Yadav (India)
I know from experience that four isn't an easy place to bat in T20 cricket and that's especially true for Suryakumar, who is coming in after KL Rahul, Rohit Sharma and Virat Kohli.
Some would find that an intimidating place to be but he has really taken to it. He can pick out unorthodox areas, is fearless, plays with a lot of confidence, you can tell that from the way he carries himself, and he doesn't go many innings without making a score.
Haider Ali (Pakistan)
Haider Ali is a player who really has something about him. Pakistan move him up and down the order but wherever he bats, he is capable of hitting the ground running.
There'll always be a lot of runs scored by Babar Azam and Mohammad Rizwan and they often face a lot of the balls in an innings, so they'll need guys like Haider to play cameos down the order.
Tim David (Australia)
David has had a different transition into international cricket, starting out with Singapore before going on to shine in the IPL and other competitions around the world.
He has had some useful cameos in his brief appearances for Australia so far and he obviously has a lot of power. He seems to be able to hit boundaries with ease.
Harry Brook (England)
Brook is an example of someone who has been brought up on T20 cricket, so smacking the ball from ball one has become second nature.
England have a settled white ball line-up so the fact Brook has forced his way in shows they see something special in him.
Finn Allen (New Zealand)
At 23, Allen is the youngest member of a New Zealand side which is ageing, so they'll need him and some of the other young guys to make their mark.
Allen could play in place of Martin Guptill, so he may be under a bit of pressure, but he's got the endorsement of the coach and this tournament is a great opportunity to show he can be a big part of this team for years to come.
