Zola watched West Ham lose to West Brom last weekend
New West Ham boss Gianfranco Zola says he is happy with the club's management structure in which he works under technical director Gianluca Nani.
The Hammers' previous manager Alan Curbishley resigned earlier this month because a lack of control over the club's transfer policy.
But Zola told BBC Sport: "I came to this club to work as a team - I want to work with the board and Gianluca Nani.
"If we need to improve certain things I'm sure they will back me," he added.
When you go down physically you also lose attention
Gianfranco Zola
"As far as I'm concerned I've got so much to do on the pitch I wouldn't be able to look after the other things.
"That is the way I have been brought up. I like working on the pitch and trying to improve what I've got and then telling the club that if we want to improve a little bit more then we need to change these things and then it's down to them."
The 42-year-old Zola officially took charge of the team on Monday, having watched West Ham slip to a 3-2 away defeat by West Brom at the Hawthorns last Saturday.
And Zola has already pinpointed his squad's fitness as an area he wants to improve.
"I was surprised how the players tired towards the end of that game. Probably if they had not we wouldn't have lost," said Zola, ahead of Saturday's game with Newcastle.
"But I told the players not to be too hard on themselves. Up to 70 minutes they were very good and looked the better team on the pitch.
"The last 20 minutes they went down physically and when you go down physically you also lose attention and that's why we conceded a third goal.
