Hero Indian Super League 2016 has seen plenty of influential individual performances in difficult circumstances. These performances have come at important junctures and accounted for some crucial points besides putting a dent on the opponents’ campaign. Here are some of the best individual displays from the league stage.CK Vineeth vs Chennaiyin FCHigh on confidence after coming on as a substitute to score the winner against FC Goa deep into stoppage-time, Vineeth proved to be the difference again when Kerala entertained Chennaiyin FC in Kochi. The Blasters fell behind to a Bernard Mendy strike in the first half before Duckens Nazon equalised in the second.With the game resting on a knife-edge heading into the final 10 minutes, up stepped Vineeth to score twice in the 85th and 89th minutes and secure maximum points and settle the high-octane south Indian derby in favour of the men in yellow. Kerala head coach Steve Coppell summed up the effect Vineeth had on the game in the post-match press conference. “CK Vineeth just being there physically has been a big psychological boost,” Coppell said.Milan Singh vs FC Pune CityOne of the finds of Hero ISL 2016, Milan Singh has put in some stellar showings at the centre of the park for Delhi Dynamos FC. The 24-year-old midfielder has become a first-teamer over the course of the season with several performances that justify his inclusion in the starting XI. One of his best performances for the Lions came against FC Pune City in the capital city.Trailing 1-0 with 11 minutes remaining on the clock, Milan managed to do what the Dynamos’ deadly attacking trident of Marcelinho, Florent Malouda and Richard Gadze had failed to: break down the Stallions’ stubborn resistance. The two-footed midfielder executed a sublime finish to help his team secure a hard-fought point.Delhi head coach Gianluca Zambrotta was effusive in praise of Milan after the game. “He is a very young and promising talent for Indian football. Since he is young he has a lot of scope to keep getting better. You need to keep working hard day by day, if he continues working hard he will keep getting better,” he said. It wasn’t the last time this season that Milan had stepped up in a crunch situation to bail out his side as Atlético de Kolkata can attest for following his left-footed screamer that played its part in helping a 10-man Delhi team secure another valuable point at home.Leo Costa vs Chennaiyin FCAfter toiling for an equaliser for most of the second half thanks to a Jeje Lalpekhlua goal, Mumbai head coach Alexandre Guimaraes introduced Leo Costa in the 61st minute to salvage something from the game with the likes of Diego Forlan, Sony Norde and Cafu, all struggling to break down Chennaiyin’s backline.With time running out in Chennai, Costa attempted one of the most audacious strikes this season - 30-odd yards from goal - and pulled it off successfully. The Brazilian’s thumping shot from range two minutes from full-time kissed the inside of the post before rippling the back of the net to earn his team a crucial point away from home and leave Chennai deflated.Helder Postiga vs NorthEast United FCHaving lost their previous match to Mumbai City FC, ATK were looking to bounce back with a win against the Highlanders and go top of the table. However, a goal six minutes before half-time by Emiliano Alfaro had put ATK on the back foot in front of a raucous and intimidating crowd of more than 30,000 thousand people in Guwahati.But cometh the hour, cometh the man and on came Kolkata’s marquee player Helder Positga from the bench at the start of the second half to equalise with a clinical header just beyond the hour mark. The Portuguese star changed the entire complexion of the game and set his side on their way to a 2-1 win in Guwahati coming from behind. His work on the pitch didn’t go unobserved, drawing praise even from Highlanders head coach Nelo Vingada, who remarked. “Helder Postiga’s introduction brought in a new angle to the game and it was difficult for us to stop him even though we had one of our players to man-mark him. He really changed the game and got Atlético de Kolkata better organised. They were better than us in the second half,” Vingada said.
