Arsenal goalkeeper Wojciech Szczesny believes the English players at Chelsea "run the club" and have brought instability to Stamford Bridge.
Since the departure of Jose Mourinho in September 2007, Chelsea have been led by seven different managers, and the club are currently in danger of missing out on Champions League football.
Amid claims the likes of Frank Lampard, John Terry and Ashley Cole wield great power in the dressing room and may have been responsible for the departure of Andre Villas-Boas, Szczesny has emphasised the importance of Arsene Wenger's unquestioned authority among the Arsenal players.
"I think some of the English players at Chelsea run the club, pretty much," Szczesny told the London Evening Standard. "They have had seven managers and it's a little bit different here. I don't think there has ever been danger of chaos with us this season.
"It's completely different at this club. In the dressing room, we know that Arsene Wenger is the boss. Robin van Persie is our captain and a leader but in the dressing room we're all even.
"All the players believe in what the manager is doing. Sometimes things don't go our way but we believe in the way the manager runs the club and the way he wants us to play football.
"We know that even if things go wrong for us, we'll still turn it around. That's what we've done in the last few weeks and I hope we can keep on doing it."
After coming from behind to win their last two Premier League games against Tottenham and Liverpool, Arsenal are now three points clear of Chelsea in fourth.
With third-placed Spurs only four points, though, Szczesny is hoping the Gunners can pile the misery on their arch-rivals.
"I would not settle right now for fourth place," he said after the 3-0 win over AC Milan on Tuesday. "We are four points behind the other North London club - I am not going to say their name - and hopefully we can challenge them.
"Hopefully Chelsea can challenge them for fourth place and I would be really pleased to see them in the Europa League next season. That would be fantastic. Hopefully they will be looking at this result and are looking over their shoulders. The momentum is with us. We won two fantastic games against Liverpool and Tottenham and we won a great game against Milan."
The goalkeeper is confident that Arsenal can improve next season and provide a stronger Champions League challenge.
"That tie was a great experience for our players," the 21-year-old said. "For some of us it is our first season in the Champions League and I'm sure that we will use that experience next year in the competition to help us go a little bit further, maybe even win it."
