Four years of planning, four years of preparation. Forty-four years of hurt and counting. And maybe the chance, at long last, for long-overdue World Cup redemption. But which team are we discussing here? England, the hosts, or South Africa, the challengers?

For there could be no more apt contest with which to launch the 12th Cricket World Cup - the fifth on English soil but the first for 20 years - than a match-up between the two sides with arguably the most torrid World Cup histories of them all.

In the (light-) blue corner … the hosts, the favourites, the perpetual laughing stocks. A team that reached three World Cup finals in the first five editions, lost the lot, and have not won a single knock-out fixture in the three decades since - as if the pain of further rejection has superseded any desire to countenance that long-awaited success.

And in the green-with-yellow-tinges corner, the quadrennial accidents waiting to happen. The team that spent the first four editions of the tournament on the outside looking in, but then - welcomed into the fold from 1992 onwards - somehow hit upon new and ever more gruesome ways to screw up their best-laid plans.

From rain-rules (times two), to last-ball sixes, via the single most storied run-out in World Cup history, South Africa - unlike England - have been a team from which great things have been expected, and on which great calamity has endlessly been bestowed.

Have those expectations now been swapped going into the 2019 edition? South Africa are now the team coasting into the competition with expectations at an all-time low, and the squad are consequently in something approaching a chilled-out frame of mind (although the news that SACA has just instigated legal proceedings against the board may yet be the start of a new means to disrupt that sangfroid).

Instead, it is England about whom the entire world is talking … and about whom everyone is doubtless preparing to burst out laughing if they fail to fulfil their destiny this summer. But, tellingly, no matter how wishful the thinking may be on that front, there is no escaping the notes of respect and trepidation that underpin every mention of the world No. 1s.

England's four-year journey from no-hopers to world-beaters has been stunning and well-documented - as many as five players still survive from the team that crashed out in the group stages against Bangladesh four years ago, but it is the transformation in mindset that has been stunning and unequivocal.

It began with Eoin Morgan's insistence, after that 2015 debacle, that things had to change - that England had to embrace players who, in the first instance, weren't afraid to fail, in order to free them up to become the attacking team they needed to be.

And it has continued with an almost Olympian pursuit of batting excellence. Citius, altius, fortius has been the message from the top. If in doubt, go for your shots. And if it goes wrong - as it has done on a handful of notable occasions - go again. England have made it their business to embrace their status as favourites, and to absorb the pressure that comes with that status, by wearing their learning lightly and projecting an impenetrable confidence in their overall direction of travel.

There's every possibility that England will once again fall short as they attempt to claim the silverware that eluded the likes of Gooch and Botham, Gatting and Gower. But the round-robin format mitigates against one-off accidents - and two notable notches in this team's recent history stand as testaments to the fact that no contest is over until it is over.

The brutality of England's defeat in the World T20 final in 2016 was followed a year later by the totality of their collapse against Pakistan in the 2017 Champions Trophy. Both matches, however, came earlier than expected in England's journey into the light. Morgan himself had always envisaged a four-year plan when it came to scraping his team off the turf after that dreadful defeat in Adelaide.

As for South Africa … who could forget the shattered minds and bodies that littered the Auckland outfield after that semi-final defeat four years ago? They perhaps felt, in that moment, that their latest and best chance at glory had been snatched by Grant Elliott's scythe through the line. And yet, the core of that squad are back for another go four years on - lessened by the loss of AB de Villiers in the interim, but emboldened perhaps by their relative anonymity and bolstered by a raft of young guns who, as Faf du Plessis pointed out in the pre-match press conference, have experience of winning a World Cup at under-19 level.

And so here we are, at the start of a potential 11 matches on the road to overdue glory. So near, so far. So often. So what's it to be this time?
