Coach Zico says FC Goa are not unduly worried about Mumbai City FC attackers Sunil Chhetri and Sony Norde ahead of their game in the 2015 Hero Indian Super League (ISL) at the DY Patil Stadium in Navi Mumbai on Sunday.In Mumbai’s 2-0 win against Delhi Dynamos FC earlier this week, Chhetri hit the back of the net twice with Norde playing a role on both occasions. On the prospect of facing them, Zico said: “It’s always difficult to play against top players but we don’t have a special plan for them but we will be alert. Sunil Chhetri and Sony Norde are top players and we know they will be there but we will have to play our game.”Goa sit atop the league table with 10 points from five matches. Their campaign had taken a big blow when they lost 4-0 against Chennaiyin FC in their third match but they quickly moved on from that defeat with wins against NorthEast United FC and Kerala Blasters FC, both come-from-behind wins. Zico was effusive in praise of his players.“It shows what we are made of. In that 4-0 loss, it could easily have been 4-2 or 4-3... It shows we are doing good work and I’m very happy with my players. To come back after that defeat, we had the strength to come back after that match and get other results,” the Brazilian said.“I always tell my players we that if we score or get scored against, it’s part of the game. It’s better not to concede but if you get scored against, we should have the strength to come back which happened in the last two games.”Overall, Zico was happy with the progress of his team. “There is a satisfaction to our doing a good performance. Very different from last year, I think at this stage we had four points. Our team is doing a great job and we would want to carry on this way,” he said.After the Chennaiyin FC defeat, Goa, known for playing attractive football up front, tightened their midfield quite a bit. Zico said that despite doing that there was no intention to compromise their philosophy of attacking football.“Our philosophy remains the same that is attacking. We have scored five goals in the last two matches and against NorthEast United FC we could have scored five-six. It doesn’t matter our philosophy remains the same.”Commenting on Mumbai’s marquee player-cum-coach Nicolas Anelka and his additional responsibility as coach this year, Zico said: “He was a great player. Lots of experience he has with different clubs. He was with me at Fenerbahçe and I wish him all the success. It’s a new role. He will be learning every day. I’m sure he will be fine and have a lot of success in his career.”
