No one wanted it to come to this. Not even the fans that held up the banner wanted to protest like this, but they were left with no choice. Something has to change.
12 years ago this would have been unimaginable. Arsenal were about to win seven games in a row and go nine points clear at the top of the Premiership with ten games to spare.
The Gunners defeated Blackburn 2-0 at Ewood Park, they had lost by the same scoreline a year earlier to throw away the title. This time they held on, and didn't just hold on, but went unbeaten, earning Arsene Wenger his third manager of the season award in eight years.

It's hard to imagine that scenario now for Arsenal supporters. The team is so far away from what they once were, it's hard to explain where it all went wrong.
If you told the protesting fans 12 years ago, they would be demanding their manager to be gone in 2016, they would have looked at you at you as if you were crazy.
But the Arsenal boss hasn't won the manager of the year award since that season, and nor has he won the title.
TIME FOR CHANGE
Arsenal supporters have every right to demand change. Especially the away fans who travel the length and breadth of the country to support their side, despite no drastic change in success.
Obviously not every Arsenal fan feels the same way. Some supporters respect that the former Monaco boss had a difficult task in steadying the ship while the new stadium was being built and paid off.
What some fans don't understand, is why the ship is still being steadied. The ship should be sailing by now.
Some people will point to the fact that Wenger has managed to win the FA Cup back to back, but does the trophy still hold the same prestige? You only have to look at how Manchester City treated their tie against Chelsea to answer that question.
It is still, of course, mathematically possible for Arsenal to win the title and Gunners legend Ian Wright believes they could still win it.
After the former Arsenal striker saw the banner, Wright said on BT Sport: "If I was a player and went over and saw that... yes, we've had a couple of bad results against Man United and Swansea but it's not over by any stretch of the imagination, the league.
"Hopefully with a bit more confidence the boys will get going again. But a 4-0 win tonight and you've got that sign I'm really disappointed to see that."
NOT ABOUT ONE RESULT
First of all, the banner wasn't about one result. So whether Arsenal won 6-0 or lost 6-0 the banner would have been shown by the away support regardless.
They don't sway their opinion just on one result, it's the results over a number of years that have brought the supporters to a conclusion that something must change.
These fans know that yes, they could go and defeat West Brom, Crystal Palace and Watford, but they also know that they're likely to buckle against Everton, West Ham and Man City.
They know this because they have watched their team throw it away many times in the last few years. Look at the last two seasons in which they have come close to a challenge but fallen away.
In 2013/14 season, they were top of the table longer than any other side, but mentally weak results away at Liverpool, Chelsea, Stoke and Everton cost them.
In 2009/10 season, the Gunners were top with seven games to go, but defeats away at Tottenham, struggling Wigan and Blackburn meant they slipped to third.
NOT LEARNING FROM MISTAKES
This is why the Arsenal fans are protesting. They're not protesting because they lost to Manchester United and Swansea, they're not just protesting because of this season, they're protesting because no one at the club are learning from their mistakes.
The weak performances in previous seasons that have already been mentioned keep happening. It took the club eight years to replace Jens Lehmann with Petr Cech. Yet they still haven't sorted out the rest of their spine.
Yes, Francis Coquelin has shown signs he can perform there, but he has also shown his inexperience, with the red card against Tottenham his latest demonstration. Robin van Persie hasn't been replaced and how long have we been talking about Arsenal needing to find a partner for Laurent Koscielny?
Wenger's excuses of oil-rich sides such as Chelsea and Manchester City buying the title may have held up for some, but surely now Leicester are top of the table they don't stand up anymore.
Even with Wenger signing just one player, they should be performing much better than Leicester, with the quality of players and the experience the manager has. Yet they're still falling short.
Former Arsenal player Paul Merson agrees.
Merson, as quoted by Sky Sports said: "If Man City don't win the league and Tottenham or Leicester do then Arsene Wenger has to go.
"If you're sitting there telling those fans - loyal Arsenal fans - that they don't need any new players at the start of the season and then you don't win the league in front of Leicester or Tottenham then I don't see how you can justify it."
Arsenal supporters pay the highest season ticket price in the league, but don't get the highest quality. The fans don't want to treat a manager who has earned them huge success in the past like this, but they don't want to accept that the Gunners are moving forward.
They can sense this is and possibly was their last chance to win the title for a long time. Pep Guardiola, Jurgen Klopp, Jose Mourinho, not to mention Claudio Ranieri and Mauricio Pochettino are all likely to be involved next year.
Arsenal fans aren't just worried about not winning the league, they're worried it might get worse.
