for me, I believe technology has played a big part.
like what I heard, Jose is one who goes to great length to know the
enemy.
he screens their play, devise their own plans.
And I believe technology aided him alot.
That's why teams know their strength and weakness as well as the
next opposing team.
Imagine, when studies can show how much ground a footballer covers,
their favourite strike rate, where they position, how they make
their runs...
simply fanastic.
