Bangladesh have arrived in Sri Lanka for their month-long tour, which will feature two Tests and three ODIs.

Bangladesh are full of confidence after their recent five-wicket win against world champions Australia during the NatWest series in England.
"We've had two very good wins - one against India in December last year and the other against Australia in Cardiff in June," said coach Dav Whatmore.
"We need a few more wins to confirm we're moving in the right direction."
Bangladesh, granted Test status in 2000, have lost 33 of their 38 Test matches and won just one, at home to an under-strength Zimbabwe earlier this year.
They have won 10 out of 112 one-dayers and their Cardiff win prompted tens of thousands of fans to pour on to the streets of Dhaka, the capital of Bangladesh, in celebration.
"With the population base we have, Bangladesh is a sleeping giant.
"It is going to take some time, but this team is going to improve," said Whatmore, who was Sri Lanka's coach before joining Bangladesh in 2003.
"I am going to share every bit of information I have on the Sri Lankan team.
"If you do a job, you do it as well as you can, no matter whom you are coaching," he added.
Sri lanka, meanwhile, have announced a new three-year sponsorship deal with Dilmah Tea, worth £1.1m.
