As Bundesliga, Serie A, Ligue 1 and Eredivisie head for their winter breaks, while La Liga returns, we look at the state of play in Europe.
La Liga is up for grabs as several sides attempt to knock Barcelona off their perch, while Serie A and Eredivisie remain wide open at the halfway stage.
PSG and Bayern Munich have continued their dominance in Ligue 1 and the Bundesliga respectively, but there has been no shortage of stories elsewhere across Europe.
The season was touted as being the most competitive in La Liga for decades, but even with five points separating first and fifth, not too many have faith in Barcelona dropping somewhere underneath second gear for the remainder of the season.
They have reached fifth gear only fleetingly - namely the 4-0 win over Real Madrid at the Bernabeu in November, a win that will go down in the history books as one of Real's most humiliating nights - but Lionel Messi, Neymar and Luis Suarez look simply unstoppable.
More importantly, Barca navigated their way through a five-game period without Messi, coming away with four wins following the Argentine's knee injury, and go into the break level on points with Atletico Madrid having played a game less.
Diego Simeone's Atletico are clicking again after several changes in the summer, the Argentine proving once again he is one of the world's top coaches as they reach half-time in La Liga with a chance of an unprecedented second title in three years.
Simeone attempted to add beauty to Atletico's brawn early in the season, but when that didn't work, he quickly returned to his roots and led the 2013/14 champions on a nine-game unbeaten run, winning seven of those.
Across Madrid, Real boss Rafa Benitez was being criticised before even losing a game, and the 'sack, hire, repeat' trend under Florentino Perez shows little sign of stopping. Is Benitez just another stop-gap? Guillem Balague thinks so. "I do not see Rafa being there next season," he said in November. "I am pretty sure that Florentino will think of something different."
They are still in touch with the title, but the problems run deeper at the Bernabeu, and all eyes will be on Cristiano Ronaldo as his future remains unclear. For Balague, it is clear as day: "We have said many times there is a strategy for Ronaldo to go to another club next season."
Elsewhere, Gary Neville's appointment at Valencia caused a stir, and the ever-expectant fans at Mestalla will want to see results soon after the new year, while Celta Vigo and Villarreal both have a real chance of a top-four spot having impressed at the halfway stage.

Pep Guardiola is on course to win a third straight Bundesliga title in his final season at Bayern Munich having dropped only five points all season, winning by three goals or more in eight of their 17 games.
Outside of Bavaria, Borussia Dortmund manager Thomas Tuchel has fit himself into the rather large Jurgen Klopp-shaped indent seamlessly, sitting comfortably in second place eight points behind Bayern and six clear of third-place Hertha Berlin.
Tuchel will be desperate to hold onto 27-goal striker Pierre-Emerick Aubameyang, who is already the latest Dortmund star to be linked with a move to Europe's finest, but it is the form of another Bundesliga striker that has most English fans taking notice.
Henry on Pep's three Ps
Thierry Henry spoke on Monday Night Football about Pep Guardiola's philosophy, and the 'three Ps'
Former Manchester United striker Javier Hernandez has more goals (17) in his last 14 games for Bayer Leverkusen than Louis van Gaal's entire side have managed in that period, prompting Bayer's CEO Michael Schade to describe the Mexican as the club's "dream transfer" at a reported £7.3m.
Bayer sit fifth, in a fight for the top-four spots alongside Monchengladbach, Wolfsburg, Schalke and Hertha Berlin.
Serie A looked much like the Premier League in late October; champions Juventus' fall from grace was dramatic, sitting 12th having won just three of their first 10 games, while Roma were at the summit, looking good for a first title in 15 years.
While Chelsea's similar plight showed no sign of stopping going into winter, Juventus have won seven games on the bounce to leave themselves three points off the lead, while Roma have won just twice in the same period to drop to fifth.
Just four points separate first and fifth in one of the most open title races in years, but a familiar face leads the way at the halfway stage.
Former Manchester City manager Roberto Mancini sits top of Serie A with Inter Milan, who have the worst goalscoring record in the top six, but the best defence in the entire league, keeping an astonishing 10 clean sheets in just 17 games.
Fiorentina, who have not won a title since 1969, and Napoli, 26 years without a crown themselves, make up the top three, setting up an entertaining second half to the campaign.
Done and dusted. No defeats, just six points dropped and just nine goals conceded, PSG will win their fourth straight French league title long before May, barring a collapse of mammoth proportions.
Laurent Blanc's side go into the winter break with a record 51 points, 19 clear of second-place Monaco, but will momentum from the domestic easy street be a help or hindrance in their quest for a first Champions League crown?
As Bayern Munich have found in previous seasons, such dominance is not always best preparation for potential meetings with Barca or Real in the knockout stages, but the feeling is this PSG side is Blanc's finished article.
Aside from PSG's rule, the story of the season is undoubtedly the rise of newly-promoted Angers, who sit third going into the winter break with a real chance of Champions League football next season.
Inexperienced but producing miracles, manager Stephane Moulin is one to look out for, but Angers face competition for a top-three place from overachievers Nice, Rennes and Lorient, as well as Saint-Etienne, Marseille, Monaco and Lyon.
Ajax sit top of the Dutch league looking for their fifth title in six years, three points clear of current champions PSV and five ahead of third-place Feyenoord.
For Phillip Cocu's PSV, the loss of Memphis Depay and Georginio Wijnaldum in the summer to the Premier League has been telling, though Luuk de Jong has contributed with 14 goals to keep them in touch.
But Ajax's spread of goals has them leading the way, with four players - Anwar El-Ghazi, Arkadiusz Milik, Davy Klaassen and Viktor Fischer - having scored seven or more goals in the league.
For Feyenoord, Dirk Kuyt hit the ground running back at his former club, scoring 13 goals in the league including two hat-tricks in two games, keeping Giovanni van Bronckhorst's side within reach of a first league title since 1999.
