PARIS (AP) — Last season, Lyon earned widespread praise for challenging big-spending Paris Saint-Germain in the French title race with mainly home-grown players.

Lyon finished second to qualify automatically for the Champions League, playing an exciting brand of football boosted by striker Alexandre Lacazette's league-leading 27 goals.

It is a far different story so far this season, with Lyon eliminated from European competition after picking up just one point in five matches in a fraught Champions League campaign, Lacazette struggling to recapture his form, and dressing-room disputes including a fight.

Lyon has failed to win its last four matches, and a 0-0 draw with Nantes on Tuesday was the final straw for long-serving president Jean-Michel Aulas, who has spoken out in a bid to stop the rot.

"We've put ourselves in a very difficult position. We failed badly in the Champions League, things came out in the press, things that belong inside the dressing room," Aulas told Canal Plus television. "It means we've got some cleaning up to do."

Lyon won seven consecutive leagues from 2001-07, and hopes were raised last season that Lyon would be competitive again.

But after 16 rounds, the club is 16 points behind runaway leader PSG, and coach Hubert Fournier is under pressure and struggling to keep his players unified.

In one reported incident, midfielder Corentin Tolisso came to blows with defender Lindsay Rose in the dressing room.

Other attitudes have infuriated Aulas — who gave key players considerable pay rises after last season — such as players snubbing Fournier when they are substituted.

"I've seen some attitudes that I don't like. We've given the players the best conditions possible," Aulas said. "We're not asking them to win all of their games, but what we do ask for is a certain intensity and team unity. It doesn't matter how talented you are, if the team's not together things will become difficult."

Aulas wants to help Fournier restore order, saying "we're going to take things in hand a little bit more," adding that the situation "is not befitting a club of Lyon's standing."

Lyon players will need to make a good impression on Saturday away at third-place Angers — one of only three sides to have earned a draw against unbeaten PSG so far this season.

Here are some other things to know about this weekend's games:

RABIOT'S CHANCE: When central midfielder Marco Verratti limped off injured against Real Madrid a month ago, it was expected to be a big blow for Paris Saint-Germain.

But Adrien Rabiot has stepped up with such assurance that he is making a good claim for a permanent place. The 20-year-old Rabiot, one of the few players developed at the club, has provided an invaluable outlet for the defense with his crisp passing.

He is also good in the air, heading PSG's opening goal in a 5-0 win at Malmo in the Champions League last week.

Coach Laurent Blanc will be doubtless relieved he did not let Rabiot leave when he pushed hard for a move in the summer of 2014.

FONT OF YOUTH: Despite being the youngest goalkeeper ever in the French first division, 16-year-old Alban Lafont is showing no nerves. In fact, Lafont is proving to be somewhat of a lucky charm for struggling Toulouse.

He kept a second consecutive clean sheet on Wednesday in a 3-0 win at Troyes, distinguishing himself with three smart saves early on and showing good composure throughout.

Lafont's next task promises to be somewhat tougher on Saturday when he faces Lorient striker Benjamin Moukandjo, the league top-scorer with 11.

NO REGRETS: Teen forward Jeremie Boga has no regrets about leaving English champion Chelsea to join Rennes on loan. The 18-year-old capped his first league start with a well-taken goal against Reims last Saturday.

"I've been waiting a long time for that," said Boga, who joined Chelsea in the summer of 2014. "I've come here to play, to improve. I'm patient, I train hard, and I've taken my chance."

Rennes coach Philippe Montanier has been impressed with Boga, who can play center forward or out wide, saying "he's direct, quick, and explosive, and has the ability to get away from players."
