I was always a fan of Mahela's captaincy, nice and aggressive for the most part but with a cool, calm authority about it... I prefer him to Sangakkara too.
But you're right Kaustav, him coming back now is more through lack of choice - and first and foremost he needs to command his place in the side as a batsman. I'm hoping he scores some runs soon. As a team Sri Lanka found some ODI form in the last two matches of the South Africa tour - and were slightly unlucky to lose the 3rd match.
Australia should comfortably win the tri-series - I guess I will have to wait and see whether it's worth going to watch the ODI in Sydney! As a fan all I can do is hope that they improve!
