Delhi Dynamos FC registered their fourth win in the 2015 Hero Indian Super League on Thursday evening and marquee player-cum-coach Roberto Carlos, who also featured in the game, was a happy man.Delhi beat defending champions Atlético de Kolkata 1-0 at the Salt Lake Stadium thanks to a Gustavo dos Santos strike late into the match. The Brazilian came on in the second half and Carlos was happy that the move paid off. “Usually the teams are slowing down in the second half, and dos Santos is very fast. So he has the ability to come in and speed it up. It’s a very important victory for us,” Carlos told reporters after the match.On his second appearance this season that saw the spectators in the stadium stand up to their feet to greet him, Carlos said: “I will thank the supporters of Atlético de Kolkata for their love. I’m very happy to play in front of them. For me it’s an honour.”Carlos continued: “It’s awesome obviously. From among the ISL grounds, Delhi obviously ours, Kerala, Goa and Kolkata have been great. Fan support has been great. This makes the player more eager to play. Once again thank you so much for all the support.”Dos Santos, who also addressed the media, said the team was more focussed this year. “Yes the team is different. This year we are chasing better things, last year it’s not that we did not want to but this year our focus is outstanding,” he said.
