Manchester City almost relied on the muscle memory that has made them consistent champions to come through a scrappy performance to set up what looks like another Premier League title.
Guardiola’s side were nowhere near their best but click on to automatic pilot when the pressure peaks to get the job done and leave Arsenal, the side in closest pursuit, facing bitter disappointment.
Inevitably it was Haaland and De Bruyne who provided the smooth link to break the deadlock, the striker being left with the simplest of chances.
It was then that deputy keeper Ortega demonstrated his quality once more, particularly with a crucial save from Son who raced clear in the position he relishes.
Ortega made a stop of such significance that Guardiola threw himself on the turf in sheer relief.
Haaland’s penalty wrapped up the three points, leaving City’s supporters in joyous celebration at the final whistle, knowing their side are now in a position they have become so familiar with and one from which they rarely make mistakes.
Arsenal must hope West Ham can somehow produce a shock on Sunday, while the Gunners concentrate on beating Everton at Emirates Stadium.
