Former champions Mizoram completed a come-from-behind 3-1 victory over six-time champions Goa in their opening Group B game of the 72nd edition of the national football championship for Santosh Trophy at the Rabindra Sarobar Stadium.
Goa skipper and India discard Victorino Fernandes opened the scoring in the 11th minute but F. Lalrinpuia equalised in the 25th minute.
Two quick goals from Lal Romawia in the 81st and 84th minute followed, which helped the 2013-14 winners seal the deal and bag all three points.
Mizoram went on top of the group with three points and lead Punjab on a better goal difference.
They play Odisha next on Thursday and Goa would hope for a better show when they face Karnataka on the same day.
Meanwhile, former champions Punjab rallied from a goal down to beat Odisha 2-1 and open their campaign with a win.
After a barren first half, Odisha took the lead in the 62nd minute through Arpan Lakra only for Sarbjit to restore the parity for Punjab in the 70th minute.
However, an own goal by Odisha's Rudra Pratap Pradhan sealed full three points for the Kuldip Singh-coached Punjab side at the Sailen Manna Sports Complex in Howrah.
In their next games, Punjab will face Mizoram on March 22 at Rabindra Sarobar Stadium while Odisha will face the same opponent in Howrah on March 24.
