I know there's probably a thread for this, but I can't be asked to look for it and opinions may have changed. After reading the "Congrats Mahela" thread, this got me thinking.
This would be my all-time Sri Lankan Test XI:
A de Silva
I know that perhaps Mendis in there seems premature but his stats are amazing and given time he will deserve to be in here. I know Fernando also seems strange, but Sri Lanka, apart from Vaas, have not had many good pace bowlers.
