Ganguly felt it was indeed a morale booster and his confidence has been strengthened after scoring 115 runs and claiming three wickets in the match.
Ganguly's sparkling 72, including three towering sixes, however, couldn't prevent Mumbai from winning the match.
Ganguly said the Bengal team had not played for last three months and the lack of match practice was evident here today.
''Though we lost to Mumbai, we put up a good show and the boys would gain valuable experience in due course,'' he added.
Ganguly played in the All India Moin-ud-Dowlah Cricket Tournament after gap of 13 years.
He said since he was busy with International schedule, he could not play much in the domestic cricket.
''I have happy and enjoyable memories about the city, as I led a One-day International here,'' he added.
