It was only a couple of weeks after beating Manchester City in the FA Cup final at Wembley that Palace were hit with a devastating sucker-punch.
It was early July and south London was eagerly anticipating the prospect of Selhurst Park hosting Europa League football for the first time.
But after Uefa deemed Palace to have breached its multi-club ownership rules – with American businessman John Textor holding stakes in both the Eagles and French side Lyon, who had also qualified for the Europa League – Glasner’s team were demoted to the Conference League.
The shock verdict threatened to suck the life out of Palace’s success before the new season had even began, with Parish describing it as “probably one of the greatest injustices that has ever happened in European football” before an ultimately unsuccessful appeal to the Court of Arbitration for Sport.
After a 120-year wait for a first major trophy, however, it was going to take more than that to dampen Palace’s spirits.
The Eagles showed no signs of feeling sorry for themselves when starting the new season by defeating Premier League champions Liverpool in the Community Shield in the now-familiar surroundings of Wembley.
But the turbulence continued with the departure of talisman Eberechi Eze, who left for a record fee to join Arsenal after five years at Selhurst Park.
And they nearly also have had to cope with the loss of star defender and captain Marc Guehi had Glasner not intervened.
The England international was all set to rubber-stamp a move to Liverpool until Palace pulled the plug late on deadline day after a move for his intended replacement – Brighton’s Igor Julio – failed to materialise.
After Guehi’s move to fell through – which would have brought Palace a fee in excess of £35m for a player in the final 12 months of his contract – the lines between Glasner and Parish appeared to blur.
It was reported that the Austrian manager, also in the final year of his deal at Selhurst Park, had threatened to quit if Parish had sanctioned Guehi’s move to Merseyside.
Glasner was left frustrated that Palace, preparing for their debut European campaign – which would include at least six additional games in the league phase of the competition – seemed willing to sanction departures rather than retain and strengthen the squad they already had.
It was clear tensions were rising behind the scenes at Selhurst Park.
