The time frame of just 4 matches in the new chapter of his glittering managerial career is all Jose Mourinho needed to make an impact at his new club.
With four wins from his first four competitive games, Mourinho is the first manager in Manchester United's 138-year history to win his opening four consecutive matches for the club.
An opening 2-1 victory in the FA Community Shield at Wembley Stadium against reigning Premier League champions Leicester last month kick-started the winning run, with 3-1, 2-0, and 1-0 wins over Bournemouth, Southampton and Hull City over the past three weeks helping Mourinho seal the record.
His record-breaking achievement marks somewhat of a comeback, considering just over eight months ago, he was sacked by his former club Chelsea after leading them to an atrocious first half of their season, which saw them sitting just two places above the relegation zone at the time of his dismissal from the club in December.
Although caretaker manager Guus Hiddink worked hard to push Chelsea up the table and steer them clear of relegation contention by seasons end, the damage inflicted by Mourinho had been done, with a final placing of 10th spot the worst the club had finished in 20 years, and the worst defence of a title the Premier League had ever seen.
However, the self-proclaimed 'Special One' was thrown a lifeline by new club Manchester United in May, announced as the successor to outgoing Dutch manager Louis van Gaal and handed the task of not only steering Manchester United back into the UEFA Champions League, but doing so by winning the Premier League.
Three games into the new Premier League season, and Mourinho looks back to his best, attracting some of the biggest names in the game to his new club, with the likes of Henrikh Mkhitaryan, Zlatan Ibrahimovic and Paul Pogba signing on to be apart of the Mourinho era.
Ibrahimovic in particular has been impressive en route to Mourinho's record-breaking run, scoring the winner in the Community Shield match on his competitive debut with seven minutes remaining, while netting three goals in the first three games of the league, sky-rocketing him to first equal in the Golden Boot table.
Any doubt of Mourinho's ability to succeed after his most recent stint at Chelsea and his suitability for the role at Manchester United has quickly been dispelled, as he now looks on to push forward and continue to break records as the season progresses.
