Chelsea hit a low Saturday with a third straight loss in the English Premier League, while Bayern Munich rediscovered its dominant form in Germany.
Although absent for the 1-0 loss at Stoke, Chelsea manager Jose Mourinho will be under even more pressure after the preseason favorite fell to just three points above the previously unthinkable relegation zone.
Bayern, meanwhile, continued its march to repeating as Bundesliga champions by beating Stuttgart 4-0.
Zlatan Ibrahimovic also scored twice as French titleholders Paris Saint-Germain thrashed Toulouse 5-0 to move 11 points clear at the top of the table.
Here is a look at Europe's major leagues on Saturday:

ENGLAND
Chelsea and Mourinho were returned to an unwanted crisis by another defeat for the defending champions.
Stoke broke the deadlock when Marko Arnautovic scored with an acrobatic effort in the 53rd minute.
Mourinho missed the away game after receiving a stadium ban for his behavior toward match officials in a 2-1 defeat at West Ham in October.
Manchester United ended its Premier League scoring drought with a 2-0 win over West Bromwich Albion from Jesse Lingard's first goal with the club and Juan Mata's penalty.
Leicester striker Jamie Vardy scored for the ninth straight league match in a 2-1 victory against Watford.
Newcastle, meanwhile, moved out of the relegation zone following a 1-0 away win against Bournemouth. Norwich beat Swansea 1-0, and Southampton defeated Sunderland 1-0.

GERMANY
Thomas Mueller helped produce goals for Arjen Robben, Douglas Costa and Robert Lewandowski before he scored himself as Bayern got back to winning in the Bundesliga.
Bayern's league record 10-game winning start ended in at Eintracht Frankfurt the previous weekend. Its 34 points from 12 games is a Bundesliga record.
''If we don't win the treble, it's a bad season,'' Bayern coach Pep Guardiola said.
Andre Schubert's six-game winning start in charge of Borussia Moenchengladbach ended in a 0-0 draw with Ingolstadt.

Four days after suffering its first defeat of the season at Real Madrid in the Champions League, PSG increased its unbeaten run in the domestic competition to 22 matches.
Angel Di Maria opened the scoring before Ibrahimovic made it 2-0 in the 18th.
Lucas scored midway through the second half, Ibrahimovic got his second of the match in the 75th, and substitute Ezequiel Lavezzi finished off the rout.
With Lyon not hosting Saint-Etienne until Sunday, Caen moved provisionally into second spot after beating Guingamp 2-1.
Also, Montpellier beat Nantes 2-1 to escape the relegation zone. Lorient demolished last-place Troyes 4-1, Ajaccio won 2-1 at Reims, and Bastia drew 1-1 at Lille.

SPAIN
Paco Alcacer and Dani Parejo scored twice each to lead Valencia to a much-needed 5-1 victory at third-place Celta Vigo.

Celta wasted a chance to pull level on points with the top two teams in the league before leader Real Madrid and second-place Barcelona play on Sunday.
Also, Eibar remained in sixth place by beating Getafe 3-1 from two goals and a penalty earned by Sergi Enrich.
Javi Guerra scored twice as 10-man Rayo Vallecano edged Granada 2-1, Deportivo La Coruna drew 1-1 at bottom side Levante, and Real Betis downed Malaga 1-0.

ITALY
AC Milan's three-game winning streak was ended by Atalanta in a 0-0 draw at home in Serie A, though 16-year-old goalkeeper Gianluigi Donnarumma was crucial to the Rossoneri earning a point.
Donnaruma pulled off two stunning saves in quick succession about an hour in, parrying Luca Cigarini's header before denying Alberto Grassi.
Bologna also won 2-0 at Hellas Verona.
