The footballing divide in Manchester is becoming clearer a month into the season.
On the blue side, Pep Guardiola is thriving at the start of his Manchester City career with five wins out of five in the Premier league.
On the red side, Jose Mourinho is discovering the toils David Moyes and louis van Gaal endured trying to live up to Alex Ferguson's high achievements during his 26-year reign at United. After opening the campaign with three successive wins, the record 20-time English champions have now lost three games in around a week.
United's 3-1 loss at Watford on Sunday ended a 30-year unbeaten run against the club based north of london.
"I feel that some individuals probably feel the pressure and responsibility too much," Mourinho said. "We started the season very well with (winning) the Community Shield and three victories in a row in the Premier league, the best start that a new manager has had at Manchester United I think.
"But was I thinking that my team was ready, perfect, unbeatableIJ Not at all. I was completely aware that we were not perfect, with lots of players who are not end products and can make their own mistakes."
"We have to improve, no doubt, individually and collectively. And that's my job."
