The epic scale of Sir Alex Ferguson’s managerial success is often spelt out in bare numbers.
In 38 years he’s won 35 major honours including 15 English and Scottish League titles, and four European trophies.
But as he sat in the bowels of Old Trafford on Tuesday night, distraught after that shattering defeat, one number will have been pounding away inside his skull: Two.
That’s the number of times he’s managed to defeat Jose Mourinho in 16 attempts.
It’s also the number of European Cups he’s won, despite 20 years of trying, at one of the world’s biggest clubs in an era when English football has never been richer.
And it’s still one less than Bob Paisley.
