#2 To avoid falling further behind Manchester City
Manchester United and Manchester City have a very unique relationship. Demarcated by city boundaries and vastly incomparable histories, Manchester United were once the dominant team in England and looked on with smugness at their poor cousins who could only dream of being as successful as the Red Devils.
All that changed with the takeover of the club by Arab billionaire Sheikh Mansour bin Zayed Al Nahyan in 2008, as access to his billions meant that United did not only get a worthy city rival but one that would soon overtake them.
United fans had to remove an offensive banner at Old Trafford mocking Manchester City by showing the number of years they had gone trophyless (35 years) following their FA Cup triumph in 2011.
Only a year later, Ferguson was made to eat his words after he had said that not in his lifetime would 'the noisy neighbors' win the league (after they purchased Carlos Tevez), which they did in dramatic circumstances as Aguero's last-minute winner on the last day of the season was enough for the club to win its first ever Premier League title at the expense of Manchester United, leading to a RIP Fergie shirt being worn by Tevez during the title proceedings.
The arrival of Guardiola (who was Fergie's prime candidate to replace him) at City has further widened the gap between both clubs, and not only is City more successful, they also play better and more attractive football than the Red Devils.
It must have been a nightmare for any United fan to watch as Manchester City made a procession off winning the EPL last season, while Manchester United lamely tagged along, finishing a dismal 19 points behind the champions.
With the club's performances thus far, there are no signs of the gap being narrowed under Mourinho, and to avoid the nightmare of further falling behind City in the pecking order, a new narrative is needed at Old Trafford, and sadly Mou shouldn't be the one to guide United through it.
