'Hysterical & hated at times - but Guardiola is already the greatest'
Pep Guardiola will become the first manager in history to win the Treble twice if his Manchester City side beat Inter Milan to lift the Champions League trophy on Saturday.
Having already achieved the holy grail of league title, domestic cup and European glory with Barcelona in 2009, Guardiola and his City players are one win away from becoming the 10th team to ever achieve the feat.
But, win or lose in Istanbul on Saturday, Guardiola is already the greatest coach football has ever known.
Not because he wins things - 16 major trophies and counting - but because he has changed football.
I recently met up with one of Europe's most coveted young coaches and the conversation turned to what made the 52-year-old Spaniard special.
"Pep gave an instruction to Joao Cancelo," the coach told me. "I heard it and all I could think was: 'I know what you are are about to do and I can't defend against it.'"
The coach said what made Guardiola so special is his search for perfection is relentless, even though it doesn't need to be. His team are good enough to win anyway. But he still pushes for 100%.
