Keep Mourinho.
Isn't he the only manager that has ever beaten Pep over a season.
If you let Pep's City get ahead of you, they could steam roll and banish you from the upper stratosphere of the Premier League like SAF did to Liverpool.
Can already see a significant shift, with them buying those Brazillian wonder kids (Gabriel Jesus and Moreno?)- what kind of Brazillian wonder kid would have signed for City 5 years ago.
And the only manager you could get to come in and stabilise the club and bring some consistency is Arsene Wenger. Now isn't that a *****.
