Roy Keane is hoping the positive aspects of his own personality will rub off on his Sunderland squad.
The former Manchester United midfielder was an all-action figure in his day, who craved success at any cost.
He appears to have mellowed slightly since stepping into management, but insists an all-encompassing desire to succeed remains an integral part of his character.
He has spent in excess of £70million over the past two years in an attempt to piece together a team capable of competing at the highest level of English football.
He believes he is heading in the right direction and is convinced that intensity and passion are key elements to creating a successful side.
"Ultimately, you always want your teams to reflect your personality," he said.
"Sometimes that takes a bit longer, especially when you are trying to build a new team, like I am.
"I think I have tried to build about 10 teams in two years, which is quite hard to do.
"But in terms of the nucleus of my squad now and the players I have got available, I am absolutely delighted.
"What we do have to understand, though, is these players need to get used to each other, need to get used to myself, the club, the expectations.
"Hopefully, in the long term, that will be good for the club, and I am sure it will be."
While Keane accepts the turnover of players during his tenure at Stadium of Light has been too high, he is delighted by the arrival of his two most recent acquisitions.
Defensive duo George McCartney and Anton Ferdinand signed from West Ham towards the end of the recent transfer window, giving Keane some much-needed competition for places at the back.
He said: "I have got more options. We came back for pre-season and we had probably four defenders on our books, maybe five.
"Now we have Anton and George coming on board, we have Phil Bardsley, Pascal [Chimbonda], Danny [Collins], Nyron [Nosworthy] - I have better options, shall we say."
