Manchester City manager Roberto Mancini has admitted he is jealous of the control his cross-city rival Sir Alex Ferguson has at Old Trafford.[LNB] Mancini revealed during his side's US tour that he would like to be given greater power in order to shape City into a team capable of challenging for the Premier League.[LNB]It is an "English style" of management Mancini admits Ferguson has earned following his quarter-century of success at United, but the Italian believes City's ambitions to challenge their rivals would be boosted should he be trusted with similar authority.[LNB]"It's important for the manager to have control over the players and the medical staff and the other situations - then it can improve," he said.[LNB]"It is different from Italy and I prefer the English style. Here if the manager loses, he is sacked and for this I think the manager needs to take every decision.[LNB]"If he makes a mistake, he pays for it.[LNB]"I agree with Ferguson but he has been at United for a long time so, for him, it is easy.[LNB]"For me, it's difficult because I have only been here for 18 months or so.[LNB]"Maybe I need to have more control of the team and the other situations. For a manager that's very important.[LNB]"Maybe if I win the Premier League this season it will be different."[LNB]Mancini's desire for greater control has seen him at odds with City's chief executive Garry Cook, but he believes their difference of opinions has helped establish a stronger partnership.[LNB]"Maybe we had a different way. Maybe because I think this way and Garry another way," he added.[LNB]"But this is normal when you work with other people and now we have a good relationship.[LNB]"We have all the same targets - we want to win and we work for this."[LNB]The resolve of Mancini's understanding with his backroom team has already been tested this summer following the ongoing saga to sell wantaway striker Carlos Tevez.[LNB]While the joint Golden Boot winner's departure is still not confirmed following the breakdown of a move to Corinthians this week, the Eastlands outfit have been busily working to secure his replacement with fellow Argentina international Sergio Aguero expected to sign soon.[LNB]Mancini would like to complete any deals to confirm his squad for the new season as soon as possible, with the Italian searching for three new names before he believes they can challenge for the Premier League.[LNB]"It's important we complete our team and can work together between now and the season," he said.[LNB]"At the moment we are not ready to play for the title. But maybe in two weeks we will be ready.[LNB]"I think we can get the players we want. I think in football anything can happen - football is strange for this.[LNB]"But if we want to compete for all competitions we must have players - but we are working for this."
