We need to bring some changes in the team and also we need to give hard training&practice to the bowlers and batsman.
1) Sehwag should be removed as his weakness has been exposed.Like how Australian team replaced dropped Heyden,we should also drop sehwag.We have to replace sehwag with Dhoni/Uthappa.
2)Suresh Raina is a talented but failed to performe well to the given chances.He should be dropped and replaced his place with Dinesh Mongia as Dinesh will be good propect for one down batsman and also can bowl leg spin.
3)Bowlers should be trained to bowl on single line for 100 balls.Mark a single line at good length area & a stump to off stick and make them to bowl on this line for 100 balls.They should be able to bowl 100 balls without fail.
4) Also train to bowl different balls like slow balls,yorkers frm the 1st spell,short pitch balls(unplayable), edge of the crease as like Makaya Nithin of south africa( He uses crease to bowl different balls)
5) Batsman should be trained to take singles,Two runs very often to move the score card and also to rotate the batsman.
6) Batsman shud be trained 2 move a foot stp forward &to bat whn bowler is bowling a good line&2 disturb his line
