Shouldn't Indian old cricketers like Tendulkar, Ganguly, Laxman, Dravid & Kumble be asked to retire ?

Indian cricket team has few very old cricheters who are overaged. They're not going to be fully fit in the next world cup after 3 years. Tendulkar, Kumble, Ganguly, Laxman & Dravid are preventing better youngsters from coming in the team. Piyush Chawla is much better than Kumble having half age of him. Tendulkar, habitual ball tamperer(caught red handed by Mike Deness & punished too), match fixing man, highly communal too(1996-97 Azhar -Tendulkar episode in print media) & great income tax evader by unfair means(Star TV reports). Ganguly is a great arrogant drama man. Laxman's footwork has gone very bad after knee operation 2 years ago. Kumble is playing for records sake only. His are neither turning at wide angles nor coming on stumps mostly. In Bangalore test 3 years ago which India lost, he gave 346 runs in two innings & got only one wicket. Pakistan's Unus Khan hit at will by reverse sweep against his negative outside off stump . Dravid is dead. Shouldn't they retire ?
