It's mind-boggling, Annis!
I'm not a fan of either club by any stretch of the imagination but I am actually looking forward to this one, as it is an early 'toe to toe' for the two managers
Mourinho to win the day for me; particularly because Pep doesn't have Aguero to lead his line. Additionally, Jose has the Premier League experience and that should be a huge advantage as Pep finds his feet this year
Prediction: Man Utd to win both the game and the Premier League this year and Man City to do exceptionally well (semi-Final at least?) in the Champions League
