Read what I said again.
We reached the final of the Carsabao cup back in December, what would he sack him 4 months later knowing that he was in line for this apparent bonus despite the fact that he had plenty of legit opportunities to sack him including the nonsense which happened in Zagreb?
Think about it...
I don't need to.
We were still on course for top 4 back in December. When the writing was on the wall and Mourinho was not going to succeed in top 4, he sacked him at the worst moment (in terms of possible success) to save a few quid.
Getting to the final in December is not when Levy would have had to pay the bones. It is in April**, after the final.
