well good initiative...mine prolly is something like this for Sri Lanka.
Dimuth Karunaratne (34)
Charith Asalanka (25) *Yet to play Test cricket. Was in the final XV for the Pallakale Test vs England as a result of an injury to Chandi*
Dhananjaya De Silva (31)
Kusal Mendis (27)
Dinesh Chandimal (33) *will still be the captain*
Sadeera Samrawickrema (wk) (27)
Akila Dananjaya (29)
Nishan Pieris (25)
Lahiru Kumara (25)
Asitha Fernando (25)
I sense a line-up like this.
Moreover someone like Sandaken(31) will remain relevant. Ambuldeniya who has lots of FC wickkets, could also come in handy as a SLA
Difficult to see Dilruwan Perera (40) in the Test team by 2022, or for that matter Pushpakumara.
Don't see a long term role for someone like Dickwella. He should only play LOIs. We lose all the reviews in the first hour's play of a Test. So no thanks, and his reckless batting to go with it
So I think Sadeera who's handy bat in FC would come good in the years to come.
Mathews (35) is already on a decline. I guess it'd be surprising to see him in the Test squad in four years time. I don't doubt his quality, but considering his fitness issues, and the not so good recent form, I doubt if he can find a place in our test team in 4 years time. But then again his presence can't be completely discarded either, knowing his overall quality as a batsman.
As far as the batters are concerned,following players could also come in handy.
Pathum Nissanka (24)
Sammu Ashan (24)
Kamindu Mendis (24)
