The original dates for submission of bid documents were March 24 (tomorrow) and Tuesday.
"Between 3rd to 21st March 2014, League organisers have recorded about 30 'Invitation to Bid' (ITB) document purchase. In terms of the numbers, this is by far the highest level of interest that any similar franchise-based sports property has garnered in India," tournament organisers IMG-Reliance said in a statement.
The league was to begin in January but had to be postponed owing to scheduling problem and lack of a window.
Promising to revolutionise the sport in the country, the league has the backing of All India Football Federation, and is likely to see big names such as former Manchester United striker Dwight Yorke, former Argentina striker Hernan Crespo and former England forward Michael Owen.
The nine cities in the reckoning are Bangalore, Chennai, Dehli, Goa, Guwahati, Kochi, Kolkata, Mumbai and Pune. Eight cities will be shortlisted.
"The mandate for winning a city team in the Indian Super League had a novelty factor wherein it's not only based on the highest financial bid, but also on the bidders' proposal of a sound plan for developing football in the catchment area they wish to bid.
"This plan would also form part of the agreement that each franchise would sign with the League, and would be expected to adhere to it.
