I rank Ohja very highly and I am sure he will get wickets if he plays in Galle.
I agree about Welagedera. He is the best exponent of swing that we have (since Vaasy) and since the decline of Mirando. Welagedera should play definitely at the Sara stadium match.
Regarding PJ - this is meant as a dose of reality and NOT as undue criticism ( although I am critical). PJ is a firm favorite of Aravinda's and he will play regardless of the odds.
I also think that PJ will play. They will want to give him another chance or two.
If only PJ can be consistent with his batting.
This is a very tough choice for me between PJ,Kaushal,Chandimal, they all got some qualities that cannot be overlooked.
Sangakara should concentrate on getting back to his top form as a Test batsman. Next year, we have fairly busy Test calender.
If he doesn't perform, I am afraid,we'll have to drop him from the squad.LOL.
Sangakkara playing as a Keeper in Tests too wouldn't be a bad idea. We've often failed in batting against quality sides like Australia in Tests. If we can get a specialist batsman, someone like Samara in that place, I guess we can get some more runs/stability in the middle order.
