diagonals from a fullback (remember them?!)
That's another thing, people lament the 4-4-2 system with those full backs, but when it worked it was superb. Prime example is Beckham and Neville on the right, overlapping and covering each other.
We should re-introduce it. It's what Pep does, he introduces his own system and everyone follows. By the time they all catch up Pep is trying something else. There's zero point everyone playing the same system. Any manager who is going to be truly successful and remembered has to cut his own furrow. Stop following all this rigid play out from the back bollocks cause Pep does it with the best players in the world who are happy to receive a ball with two men marking them.
