Shakib Al Hasan - He is Bangladesh's best ever player. I believe this places a huge responsibility on his shoulders. If he can get a bit of support from a few of the other players he could have a starring role in the World Cup. As a world-class player in a weaker team he'll get loads of opportunities to perform with both bat and ball so he should be right up there in the wickets and runs charts at the end. Also he has gained some valuable time playing in the Big Bash with the Melbourne Renegades which will help him in terms of readiness for the local conditions. Of course he'll have to play off the back foot a little more than his does in the sub-continent conditions but he can still be a very clean striker.
Shane Watson - It's time for Watson to shine. He has the ability and the experience but most importantly he looks like he is going to get the opportunity to bat at Number 3. This is probably his preferred spot and coming in behind David Warner and Aaron Finch he is going to get a good platform to really build an innings. His fitness is always a talking point but he looks to be tracking nicely and the overs he has been bowling have been better than handy.
