Victory's 3-2 win over Sydney FC on Sunday afternoon was their first victory in the Big Blue since February 2014.

However, the occasion also marked the first time in the teams history they had been undefeated in their opening four games of the season and now sit top of the ladder.

Melbourne Victory coach Jeff Hopkins says their start to the season is due to the belief the team has. 

"I think there is a belief coming to the team now that we are a good side, that we can win games and since we came back we've made sure it wasn't about just getting a good player in," he said.

"We want good people at the club and good characters.

"We have a fantastic bunch of players, that have gelled really well and all get on together but it's not just the social, they take that out onto the field with them," Hopkins said.

It hasn't always been easy for Victory, who haven't finished in the top four since the 2014 season, but things have been looking up this season. 

However, Hopkins knows despite having confidence, his side needs to still improve in some areas on the field. 

"There are a number of things we need to improve on and there is a mentality that we want to get better every day," he said.

Melbourne Victory face faces bottom of the table Western Sydney Wanderers on December 2 from 4pm AEDT.
