Brazilian midfielder Bruno Pelissari's individual brilliance saw Chennayin FC edge past Kerala Blasters FC 1-0 in Kochi on Sunday to all but ensure a place in the semi-final of the Indian Super League.
Pelissari's 87th minute strike ensured Marco Materazzi's men maintain their pole position in the eight-team league table with 22 points from 12 games - six points clear of second-placed Atletico de Kolkata.
Blasters still hold onto their fourth place in the table with 15 points from 12 games.
There weren't too many eye-catching moments but 'super-sub' Pelissari's struck just 13 minutes after being introduced into the thick of things.
Blasters had earned a corner at the other end but failed to do much with it. Pelissari received a clearance from the corner kick at the middle-third in his own half. It was the start of 50 metre sprint through the middle as rival defenders chased shadows.
He had support on the right but decided to wait as he got the ball to his left-foot and swerved a left-footed in-swinger into the net as veteran goalkeeper Sandeep Nandy had a puzzled look on his face.
The 61,000 partisan crowd went into pin-drop silence as they simply couldn't believe what hit them.
Chennaiyin, who were playing without their talismanic Brazilian Elano Blumer, showed that they have solid bench strength as they snatched all the points in a difficult away game.
It couldn't have been better for the team's co-owner Abhishek Bachchan, who was seen in the VIP box along with his wife Aishwarya Rai Bachchan.
For Blasters, their frontman Iain Hume had the best scoring opportunity immediately after the change of ends when Stephen Pearson and CS Sabeeth combined well to execute a defence-splitting through ball.
With Chennaiyin's French goalie Gennaro Bracigliano coming out of his charge, Hume's placement in haste was off-target.
Blasters also received a setback when their skipper-cum-manager David James pulled a hamstring and was replaced by Nandy as early as the 20th minute of the match.
