India coach Greg Chappell has come in for heavy criticism after allegedly making an insulting gesture to fans.
Chappell's dispute with Ganguly did not go down well in Calcutta
Newspapers claim the incident occurred on Thursday as the team returned to their hotel from practice in Calcutta.
The city is home to Sourav Ganguly, who was recently sacked as captain after a public row with Chappell.
"Indian fans might be a tad too emotional for Chappell's tastes. But they don't deserve such disrespect," The Times of India commented.
"By his extravagantly tasteless gesture, the legendary Australian cricketer has virtually guaranteed that the debate would now be on him rather than the overtly sentimental crowd."
The Hindustan Times showed a picture of a finger thrust out of the window of the team bus, which it claimed was Chappell's.
But a team spokesman dismissed the allegations, saying: "Chappell had injured his finger during practice and he said he was just attending to it. He did not gesture at anybody."
Chappell has been subjected to intense media scrutiny since his appointment earlier this year as the successor to New Zeaander John Wright.
The 56-year-old has a contract which lasts until June 2007, but results since he took over have been mixed.
They were beaten in the finals of two triangular one-day series, but then thrashed Sri Lanka 6-1 on home soil.
India are currently involved in a series against South Africa and trail 2-1 with one to play after suffering a 10-wicket defeat in Calcutta on Friday.
Following Monday's final game, they will then begin preparations for three Test matches against Sri Lanka, with Ganguly back in the squad for the opening game, which starts on 2 December.
