The 2010 I-League 2nd division was the third season of the second tier of the I-League, the highest football league in India. It commenced on 26 March 2010 with the first matches of the first round and ended in early May 2010 with the last matches of the promotion round. All matches are played in three venues at Delhi, Bangalore and Tripura.
The first round was competed by 21 teams, which have been divided into three groups with seven teams each. The two teams relegated from I-League directly played in the final round.
Each team competed a single match against every other team of its group. The best two teams from each group advanced to the final round.
Malabar United and Hindustan Aeronautics from Group A, SESA and ONGC from Group B and NISA and Oil India from Group C qualified for the final round. They will be joined by the sides having been relegated from the 2008–09 I-League, Mohammedan Sporting from Kolkata and Vasco from Goa. As in the first round, each club will play a single match against every other team of the group. All matches will be played at Bangalore.
Eight teams will vie for a place in the next year ONGC I-League as Second Division final round goes underway from 30 April at the KSFA Stadium, Bangalore.With two last year relegated teams (Mohammedan Sporting and Vasco SC) and with six qualifiers from the preliminary round viz. NISA (Manipur), ONGC (Mumbai), Sesa Football Academy (Goa), Oil India (Assam), Malabar United (Kerala) and the local side HAL (Bangalore) the final round is all set to be a blockbuster event.It will be clash of two Goan outfit in the opening match as Vasco SC will take on their city rival Sesa Football Academy that will kick off at 1400 hrs, while HAL will host Malabar United in the second encounter of the day that will start at 1600 hrs.The preliminary round performance will surely boost all the qualifiers but final round is totally a different ball game and it was clearly seen in the last year's final round, when Sesa Football Academy after putting an impressive display in the first round, went on to go down in all the crucial final round matches.The most surprising team of the lot was without a doubt Kerala based side Malabar United, who kept their domination in the Group A even with the likes of HAL, SBT and BEML.[1]
The best two teams from the final round will qualify for the 2010–11 I-League.[2] [3]
