"He does not deserve a place in the Test side. His rib cage weakness has been exposed. But he can comeback as a One-day player provided he improves his fitness and attitude," Dungarpur told reporters on the sidelines of the Challenger Series here.
Ganguly was effectively sacked as captain after the national selectors appointed Rahul Dravid for the forthcoming One-day series against Sri Lanka and South Africa.
Announcing the decision, BCCI Secretary S K Nair said the selectors' unanimous decision had nothing to do with Ganguly's injury called 'mild symptoms of tennis elbow' which prevented him from playing the Challenger Series.
Dungarpur termed Ganguly's captaincy as "reasonable" but rued that the Kolkatan "faked injuries" and "made sure left handers did not come into the Indian team" to preserve his own slot.
"Unfortunately he fakes injuries, whether it was in Mumbai or in Nagpur or in Multan. It is a pigmentation of imagination of the worst kind," Dungarpur said.
"When a captain fakes injuries, I am not too sure ... I mean, if a player is frightened of the thing called cricket, I say please give up playing cricket."
Dungarpur also said the feeling of insecurity led Ganguly to play "the game of elimination".
"He was reasonable as captain, but unfortunately he had his likes and dislikes. Players like Hemang Badani ... he (Ganguly) saw to it that left handers did not come into the team.
"He played the game of elimination."
When mentioned about Ganguly's record as the most successful Indian captain, Dungarpur said he owed it to the presence of batsmen like Sachin Tendulkar in the team.
"When there is a batsman like Tendulkar, anyone can be the captain. In Melbourne (in 2003-04), before he went into bat, he said 'bowlers are getting me out outside the off-stump, I will not play one shot on that side'.
"You need such determination as a player."
Should the captaincy go to Tendulkar again?
"He doesn't want to be. If he wants it, where is the question of discussing (other names)? Unfortunately, he wants 10 Sachin Tendulkars in the side. He wants unconditional commitment from each member in the side.
