Thierry Henry and Arsene Wenger with the Premier League trophy
Arsenal's incredible unbeaten season in 2003/04 is one of the best achievements in Premier League history...or is it?
talkSPORT's Adrian Durham has argued that the Invincibles campaign under manager Arsene Wenger was actually a failure.

Arsenal went an entire Premier League season without losing a single game in 2003/04 - but Durham has questioned how much of a success it actually was
The Gunners won the Premier League title in 2004 by going an entire 38-game term without losing a single game.
They were the first club to do so and remain the only club to do so, with that year a huge moment in English football.
26 wins, 12 draws and 0 losses. That's how Arsenal ended the season, with a squad that included Thierry Henry, Patrick Vieira, Robert Pires, Dennis Bergkamp, Ray Parlour and more stars.
But Durham thinks that Wenger and his team should have achieved more and that their record success isn't all that...
Why Arsenal's Invincibles season was a failure
Speaking on the latest episode of the talkSPORT Daily Football podcast, Durham tore into Arsenal's unbeaten campaign.
"The 03/04 season is a failure from Arsene Wenger," Durham stated amid a discussion of the Frenchman's 30th anniversary of the start of his Gunners reign. "And I'm going to explain why...
"Yes, winning the Premier League title in 2003/04 is a success, you can absolutely say that, but that season is a failure.
"They drew 12 of 38 games and the reason they did that was because, pre-season, Arsene Wenger had predicted that they would go unbeaten and they became so obsessed with this.

"Drawing became his speciality. They couldn't beat Portsmouth that season, home or away, and relied on a massive dive from Robert Pires to get a point to maintain the unbeaten run.
"They put so much into going unbeaten, the energy they put into the 38-game unbeaten run - and in isolation it's fantastic, you've won the title, you're unbeaten.

Durham thinks Wenger's obsession to go a whole season unbeaten actually hampered Arsenal's campaign
"But have a look at what the knock-on effects were from that mentality, the energy spent on that mentality because the manager had made a stupid prediction."
What was Wenger's prediction?
Durham believes Wenger's 'obsession' with going unbeaten actually hampered their success, leading to 12 draws, rather than more wins.
Wenger predicted in 2002 that: "It is possible to go through the whole season unbeaten. If you don't aim for perfection, you can never achieve greatness."
He went on to achieve that greatness with Arsenal in the following season, revealing later that he had implanted the idea of going unbeaten into his players' minds in 2002, albeit with them complaining about the pressure.
The legendary manager said: "I had asked them already to win the league unbeaten. I thought it could be done.
"They said I had put them under too much pressure by asking them not to lose a game [in the 2002/03 season]. But I said again: 'Look, I think you can do it, you just need to really want to do it.'

Wenger had it drilled into his players' minds that it was possible to pull off an Invincible season, and they did
"That shows that sometimes you need to put the seed of an idea in the brain a year early, then be patient until it comes out. Then it's important to stick with it, and not back down.
"I wanted to stick to what I believed, that we could do it, because for me the most difficult thing at the top level is consistency."
Could Arsenal have won more?
Wenger made his dream a reality, lifting the Premier League title - something that then took 22 years for Arsenal to replicate.
They scored a league-high 73 goals in 38 games, as well as conceding the fewest goals in the division, with 26 let in.
But with a team that good at both ends of the pitch, how come they didn't win anything else that season?
The Gunners were knocked out of the Champions League by Chelsea in the quarter-finals after losing at home in the second leg.

Arsenal also lost in the FA Cup semi-finals to Manchester United and the League Cup semi-finals to Middlesbrough.
"They went for four trophies, they won one of them and missed out on three of the four," Durham concluded.
"The 03/04 season, with the players they had and the football they were playing, they should have been the European champions."
