Not a week goes by without a selection of big European fixtures to sink our teeth into nowadays, and this weekend served up several treats in the form of Atletico Madrid vs. Valencia, Liverpool vs. Tottenham Hotspur and Monaco vs. Lyon. These games in particular have shaped this week's edition of the rankings.
The rankings are a season-long measurement of clubs, tracking teams throughout 2017/18 and taking into account results from all competitions.
Sides that have lost the fewest games naturally rank higher—though the strength of opposition met in a loss is considered—and both UEFA Champions League form and presence are used as tiebreakers for those with similar records. Teams that gather big wins against strong opposition get a boost.
20. Marseille (New!)
A run of seven wins in eight games brings Marseille into the ranking at the expense of Schalke 04, who lost and therefore drop out.
19. Bayer Leverkusen (-1)
Leverkusen's draw with SC Freiburg on Saturday was rather feisty, with the yellow cards outweighing the goals by a score of eight to zero.
18. Roma (+1)
AS Roma dragged themselves out of a seven-game winless run the hard way, winning at the eighth attempt against Hellas Verona.
They scored the only goal of the game inside the first minute, wasted numerous chances to extend the lead and placed themselves in jeopardy thanks to a Lorenzo Pellegrini red card...but they won. That, after what's happened over the last few months, is the salient point.
17. Lyon (-1)
After 30 minutes at the Stade Louis II, things were looking pretty good for Lyon. Holding a two-goal lead over Monaco and in complete control, a return to second place looked on the cards.
Things slowly unravelled, though. They conceded three goals in the following 60 minutes and lost to a team that ended the match with 10 men.
Shall we call it character building?
16. Valencia (-1)
Over the last three La Liga matchweeks, no team has matched Valencia for poor form. They've lost all three games and lost their way a little.
15. FC Porto (+2)
FC Porto's 3-1 win over Braga on Saturday widened the gap between Portugal's top three and the rest, and combined with Sporting CP's loss to Estoril, it has put the Dragons in a strong league position.
14. Inter Milan (-2)
It's five draws in a row for Inter Milan, and it's only a matter of time before that goes from "irritating but not damaging" to "problematic."
13. Lazio (Stay)
Lazio play Genoa on Monday evening at the Stadio Olimpico. A win can take them four points clear of Inter in the table.
12. Real Madrid (-1)
The season just gets tougher and tougher for Real Madrid fans. Watching Giampaolo Pazzini's shot trickle over the line for Levante on Saturday must have been rough. The defending? Still shambolic. The team mettle? Still non-existent.
11. Chelsea (-1)
Chelsea's season has been downright bizarre so far, with the odd horrific result permeating an otherwise respectable set of results.
The latest horrific one arrived on Wednesday, when the Blues fell 3-0 at home to Bournemouth. Cherries striker Callum Wilson revealed after the match they targeted Gary Cahill as he was seen as a weakness, per BBC Radio 5 live (h/t Metro). It wasn't the first time he's looked poor this season.
10. Tottenham Hotspur (+4)
Finally, Tottenham's form against the Premier League's top sides has begun to pick up. It may not have been particularly smooth sailing on Sunday, but a point at Anfield is positive; add it to the three they earned off Manchester United in midweek, and you've got yourself a successful week's work.
9. Liverpool (Stay)
Liverpool have managed to squeeze an entire campaign's worth of nerve-fraying for supporters into just over half a season. Any more drama from here—and we're fairly certain there will be plenty—is a bonus.
For 75 minutes they were defensively stout and looked set to hold off Tottenham's onslaught; people were whispering about a "new-look Reds." But the last 15 were utter chaos; classic, typical Liverpool.
8. Manchester United (-1)
United visited Wembley Stadium to play Spurs last Wednesday and conceded after just 11 seconds. It set the tone for a pretty horrid performance, with the Red Devils second to almost every ball and struggling to contain their north London hosts.
A follow-up 2-0 win over Huddersfield Town, who are in the Premier League relegation zone, isn't even close to enough to stop them falling down the rankings.
7. Atletico Madrid (+1)
This weekend saw Atletico make second place in La Liga very much their own by defeating Valencia and opening a nine-point gap on the two clubs immediately below them.
They're still miles off leaders Barcelona, but that won't concern Diego Simeone right now. A healthy lead on fellow top-four challengers allows them to rotate accordingly and attack the UEFA Europa League.
6. Napoli (Stay)
Since the calendar flipped into 2018, Napoli have done nothing but win and Dries Mertens has done nothing but score.
He's got four in three, having recently broken a league goal drought that stretched months, and the Partenopei are responding in style to the weekly pressure of Juventus winning earlier in the day.
5. Juventus (Stay)
Sassuolo signed centre-back Mauricio Lemos during the closing stages of the January transfer window, with the Uruguayan saying: "Serie A is the perfect place for a defender to improve," per Football Italia.
We presume he learnt a lot on Sunday as Juventus crushed his team 7-0 on his debut.
4. Paris Saint-Germain (Stay)
It was a case of happy travels for PSG last week, as they scored six goals in the space of two matches on the road to continue their relentless season.
The 3-0 victory over Lille on Saturday was a thrilling affair, with counter-attacks from both sides making for great viewing, but eventually the overwhelming quality of the capital side rang true.
Giovani Lo Celso, PSG's new up-and-coming midfield general, scored a spectacular chipped goal that stands a must-watch for any fan.
3. Bayern Munich (Stay)
Bayern had their three-point haul in Mainz wrapped up by half-time on Saturday. Franck Ribery and James Rodriguez strikes were enough to put them well clear of the Bundesliga strugglers.
The result places Bayern 18 points clear at the top of the league, and it has resulted in another deluge of questions over whether Jupp Heynckes will be sticking around for longer than just this season. His responses are becoming quite amusing.
2. Manchester City (Stay)
Manchester City battered West Bromwich Albion in their midweek fixture as expected, but they then surprised everyone by failing to beat Burnley on Saturday.
The context to every result is key, though, and had Raheem Sterling not missed from a seemingly impossible position and wrapped the game up with a two-goal advantage, we'd be talking about a stellar performance that earned the result it deserved.
1. Barcelona (Stay)
Ernesto Valverde took a calculated, presumably fitness-based risk on Sunday as he benched Ivan Rakitic, Lionel Messi and Jordi Alba for the Catalan derby at Espanyol. It almost backfired.
La Blaugrana ended up walking away with a draw, with Messi parachuted in to set up the equaliser, which is fine in their situation, as it merely matched Real Madrid's result on the weekend.
