Bruno Lage's revolution began in a nondescript room at Wolves' training ground on his first look at Compton last July.
The former Benfica manager was checking out his prospective new base and when he had been given the tour, Nuno Espirito Santo's successor asked if he could see the presentation suite. To his surprise, he was told no such room existed.
Lage made clear that if his methods were going to pay off, that would need to change. So once he had accepted the job, Wolves' staff got to work, identifying a classroom that had been previously used for education sessions for academy players.
Computers and plastic chairs were removed and replaced by upmarket leather seats and a giant touch-screen, which Lage uses to illustrate his ideas.
It has been quite a change for the players, who were used to a single pre-match meeting under Nuno. Now, these gatherings take place at least twice a day.
Lage will stand at the screen and explain what he wants. Training — with a strong tactical emphasis — usually lasts an hour, after which the defenders, midfielders and forwards will separate for meetings with different coaches.
These analysis sessions sometimes occupy more time than the training sessions, and Lage, 45, will occasionally conduct meetings with individual players in his office to discuss a particular tactical matter.
Goalkeeping coach Tony Roberts is the only non-Portuguese member of Lage's team and is also in charge of set-pieces.
First-team coach Carlos Cachada works closely with a defence who have conceded 17 goals in 23 league games. Only Manchester City, who have let in 14, have a better record, which shows Lage has restored the mean streak that disappeared in Nuno's final season.
'Boys, when you play the other teams, they need to feel we are not nice guys,' Lage told his players before the start of the season. 'They need to feel you are a hard team to beat.'
The result is that Wolves are seventh in the Premier League, six points behind fourth-placed Manchester United, with two games in hand. Though Nuno's first three years at the club were exceptional, last season was hugely disappointing. For Lage to have rebuilt so effectively, in his first senior role in English football, is remarkable, and if he can keep it up he will be a contender for Manager of the Year.
He has stuck to some of Nuno's key principles, such as the three-man defence and the faith in his predecessor's key lieutenants Conor Coady, Ruben Neves and Raul Jimenez.
However, although the overall picture may look similar to Nuno's era, the finer details are quite different.
Whereas Nuno would stand on the sidelines observing sessions, Lage is at the centre of the action — cajoling and encouraging. While Nuno was hugely respected by the majority of his squad, he could also appear distant and aloof. Lage is far more affable and has a sharp sense of humour that has made him popular with club employees.
One of Nuno's non-negotiables was that the squad had lunch together at the same time, after training. Lage has not brought back that tradition and there are no rules about when the players use the canteen. Lage certainly puts the hours in, arriving at Compton at breakfast time and often not leaving with his staff until 6pm.
With his wife and children still living in Portugal, he has thrown himself into his new job — and expects similar commitment from his players.
His pre-season programme, comprising double sessions, certainly raised eyebrows. The squad were put through their paces in 29°C heat in Marbella — and at that stage the players were yet to be convinced about their new boss. Not that he was going to compromise.
'My players only need 30 minutes with me to understand the way I am,' he has said. 'Either you go with me or I need to find someone else.'
Lage has been true to his word. Despite his thrilling attacking play, he grew frustrated with Adama Traore's difficulty adapting to his tactical ideas and now the winger has rejoined Barcelona on loan.
Defender Willy Boly was also available for transfer in January and forwards Rafa Mir and Patrick Cutrone have both been moved on.
Yet Max Kilman has developed into one of the most promising defenders in the country under Lage and is on the cusp of the England squad.
Rayan Ait-Nouri is a far smarter player this season than last and if Pedro Neto hits the ground running when he returns from injury, then European football is a realistic target.
If Wolves can achieve that, then the highlights on Lage's giant screen will certainly be worth watching.
