We did not pick Dhanushka Gunathilaka in the squad and that is a mistake IMO. In the concluded LPL, he was the best player of pace out of all players, including overseas ones. Only time he was in trouble was against slower balls and slower bowlers early on. He should have partnered DK IMO. Kusal Perera and Dasun Shanaka should never be in the test squad IMO. Looking at available squad
Dimuth Karunarathne* (L)
Oshada Fernando (R)
Kusal Perera (R, wk)
Kusal Mendis (R)
Dinesh Chandimal (R, wk)
Dhananjaya de Silva (R, OB)
Niroshan Dickwella+ (L, wk)
Wanindhu Hasaranga (R, LBG)
Suranga Lakmal (R, RFM)
Kasun Rajitha (R, RFM) / Vishwa Fernando (L, LFM)
Lahiru Kumara (L, RF)
is the likely XI. There is bit of a cloud regarding Oshada's fitness, and if it is the case everyone might move one place up and Thiri may come at #5 (praying not to happen). If the pitch shows even a bit of spin, Embuldeniya might replace a fast bowler.
