The problem for the rest - Manchester United, Liverpool, Arsenal and perhaps Spurs - is that Mourinho is certain to address his own side's biggest weakness.
That is the lack of a Ronaldinho, a Shevchenko, a van Nistelrooy or an Henry.
If Jose gets his man, next season's title chase will be as clear-cut as ever.
Liverpool? The same applies.
The only way to make best use of talents already in place is for Liverpool to find an Ian Rush Mk II.
