Real Madrid went on to dominate football for the following decade, with the team Mourinho mostly built.
He'll surely improve the shitshow from last season and there will be new motivation in the squad with a coach like him. I think however that this will all fizzle out as soon as the first negatives hit the squad.I think Mou will do well for them.
They are going to improve their defence and get in a lot more height/power to their team which has come back around as being important again.
