Mumbai City FC at last registered their first win of the 2015 Hero Indian Super League when they beat in-form Delhi Dynamos 2-0 at the DY Patil Stadium on Wednesday evening but assistant coach Oscar Bruzon wasn’t overly happy and said one win wasn’t enough and that they needed more such performances to get their campaign going.Speaking to the media after the match, when asked whether it was his team’s best performance so far, the Spaniard said: “Following the result yes, following the attitude yes, but it’s nothing it’s just one win so we cannot be happy. We need to think about the next game. Actually I'm very confident about the team, we have one of the best squads in ISL now it's time to demonstrate and not talk.”Sunil Chhetri scored a brace in his team’s win and Bruzon was all praise for the India striker. “Sunil by nature is a very natural player. He can be one of the best options for the striker position. Today he was like a fish in water, he was comfortable, combining very well in the front with Singam Subash Singh, Jaun Aguilera and Sony Norde,” Bruzon said.Of all eight teams, Mumbai are the last to pick up a win and now they host FC Goa on Sunday. When asked if the win on Wednesday could kick-start their season, Bruzon said: “Absolutely, we need to keep up the momentum. Very confident with the team. Today we played with a fit team and with a model that me and Nico [Nicolas Anelka] wanted for the game. Still have three more games to finish the leg. Let's not think that Goa will come with one less day of rest. So it’s going to be positive for us.”Had Mumbai City FC found the right combination at last? “Yes. Today the players perfectly understood their tasks. Everybody was committed to the club, the team especially with the emergency level. I'm happy to celebrate this win,” Bruzon said.
