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.
