a trick i have used suxxessfully, is write down the defauly line up and change the players u dont want with the ones u do buy crating them in teram management. I also find if u pick all batsman and only 4 bowlers then the computer has to make all your bowlers in to the defauly team line up for a match. I will always put in a crertain amount of bowlers, so if u oly pick four in your 20 man squad, they will be in.
