Pep Guardiola has masterminded his way to four Premier League titles and many argue he has changed the fabric of English football in the process.
His tactical nous has been clear for all to see at Manchester City, as it was at Barcelona and Bayern Munich. When he first arrived at the Etihad, some questioned whether his ethos would work in the Premier League.
Most notably, he brought in inverted full-backs during the early years of his tenure. This was mocked by some but those critics have since vanished.
