Pep Guardiola has said repeatedly his team could not win four trophies this season. Never did he think he would be proved right in circumstances quite like this.
Guardiola’s Manchester City were downed here by Irishman Will Grigg 10 minutes from the end. Previously Grigg was known only for a song written and sang in his honour by Northern Ireland fans during the European Championship of 2016.
He barely played in that tournament but now he has become the second Wigan player to end City’s FA Cup hopes in the space of five years. Ben Watson’s goal won Wigan the cup in a memorable final in 2013 but they were a Premier League club back then. Now they play in League One.

Will Grigg fired home from the edge of the box to secure Wigan victory. For more graphics and statistics, see Sportsmail's briiliant Match Zone feature here.
So Grigg was the hero but much of the real story was written here in the last minute of the first half when City midfielder Fabian Delph was sent off for tackle on Max Power.
It was a poor tackle and worthy of a red card. Delph was not in control.
But Guardiola was incensed by the fact that referee Anthony Taylor appeared ready to show only a yellow card before pressure seemed to arrive from Wigan players and coaching staff.
That simply proved too much for Guardiola. The City manager has recently campaigned for an end to bad tackles but here he was moved to argue with Wigan coach Leam Richardson on the touchline before clashing with opposite number Paul Cook in the tunnel.
Caught on BBC camera, the two men were kept apart, to some degree by Peter Reid, coaching these days at Wigan on a voluntarily basis. If Reid’s blood was up in a manner reminiscent of his days haring around muddy English midfields then it is unlikely that he was alone.

GRAHAM POLL – VERDICT ON DELPH'S RED CARD
Manchester City’s Fabian Delph was sent off by referee Anthony Taylor despite the referee initially taking out his yellow card following Delph’s reckless tackle on Wigan’s Max Power.
The decision to dismiss the City player was not wrong but appeared to be influenced by a huge posse of Wigan players who surrounded the Manchester-based referee.
Appearances can be deceptive and it is far more likely that one of Taylor’s team of match officials was the one who communicated that the foul challenge warranted a red rather than the yellow he initially took out.
Whatever the reason for his change of heart it was poor practice. As for the decision itself, given the pace Delph went into the challenge and the fact that he had his studs raised well off the ground, I felt the red card was correct.
Pep Guardiola has been asking for players to be protected – meaning dismissals for these dangerous tackles – but he probably didn’t want the first to be for one of his players.
In the second half, City dominated but could not score. Wigan were heroic in defence. And, as dreams of a quadruple slipped away, the niggle on the touchline did not. Still the two benches exchanged words but on this occasion — as rare as it is — Guardiola’s team could not manage to have the last word on the field.
Wigan, backed by a decent crowd, had looked dangerous when they did move forwards after City had created an early chance in the second minute.
Key to their forward movements were the efforts of former Manchester United player Nick Powell. Tall and rangy, Powell troubled City when he got in to his stride in midfield and one run forward saw him drive a shot into a defender’s legs just as City defenders were starting to panic.
Not that Guardiola’s backline needed much encouragement to get themselves into a flap and the culprit on two early occasions was the Brazilian Danilo at right back.
First he let the ball dribble through his legs on his own six-yard line as Gary Roberts lurked and then, a few minutes later, he lost the ball to Will Grigg and, as John Stones backed off, the Irishman drove a left-foot shot high in to the side netting from an angle.

Stones looked briefly to have tweaked something and that would have been a blow for Guardiola ahead of Sunday’s Carabao Cup final. The City defender seemed to run that niggle off but Wigan’s Powell was less lucky midway through the half.
Powell seemed to injure his hamstring during one sprint forwards and his night was to end in the 26th minute. That was a really big setback for Wigan and it robbed them of some of their impetus.
Paul Cook’s team still had their moments but City dominated the later stages of the first half. The closest they came to scoring came on the half hour when Stones headed down a deep cross intelligently and Fernandinho somehow lashed the ball high into the crowd from no more than 10 yards.
There were other moments for City, too, and Walton saved brilliantly from Aguero in the 45th minute, diving high to his right to touch a rising drive over.
That was only a prelude to real drama of the half, though, and Delph’s red card for a lunge on Power meant that Wigan began the second half with a greater chance to win this game than they ever may have dreamed of.
The shenanigans in the tunnel as the players disappeared for half-time were caught on camera and served to underline just how aggrieved Guardiola felt. When the second period began, he merely had to focus on ensuring his team did not lose.

Kyle Walker replaced Leroy Sane to add some security to City and the hour mark came and went without their goal coming under undue threat.
City continued to dominate the ball despite their numerical disdavantage even if, as in the first half, they struggled to create chances. David Silva did play Aguero through in the 63rd minute but the City striker could not control the ball and the opportunity passed.
Soon Silva departed — no doubt with Sunday’s meeting with Arsenal in mind — and was replaced by Kevin De Bruyne. The Belgian’s first contribution was to flash a low cross towards Aguero but Dan Burn cleared.
With 20 minutes to go, the game was being played almost entirely in Wigan’s half. It was they, not their opponents, who looked a man light.
Nevertheless, with 10 minutes left, Walker inexplicably let the ball run under his foot and turned to see Grigg running away from him. Grigg’s finish across Claudio Bravo with his right foot was superb.
