The MLS playoffs are here once more.

Los Angeles FC cruised to the Supporters' Shield title, but the path to MLS Cup glory is far from straightforward even for the league's outstanding team.

Since 2011, only Toronto FC have successfully followed up a regular season championship by conquering the postseason.

Will LAFC join them, or can Bob Bradley's men be stopped? We take a look at the key issues surrounding the leading contenders heading into the playoffs.
 

ARE LAFC AND CARLOS VELA THE BEST EVER?

The above statistic may make for uncomfortable reading for Shield winners LAFC, but no past regular-season champions have been able to match the standards set by Bradley's side.

Toronto broke a points record that had stood for 19 years when they earned 69 in 2017, yet the New York Red Bulls bettered that last year and the new benchmark of 71 was topped once more by LAFC, a late-season slump merely limiting the runaway leaders to 72 points.

Carlos Vela was key to the team's achievements this year and any side hoping to stop LAFC must somehow master the Mexican. He scored a record 34 goals, including a final-day hat-trick, and will aim to echo Josef Martinez, the previous record-holder in 2018, by making his mark in the coming weeks.
 

CAN ZLATAN IBRAHIMOVIC AND THE GALAXY STOP THEIR RIVALS?

Having missed out on the postseason last year, Zlatan Ibrahimovic was rather bold - perhaps unsurprisingly - as he slammed the playoff structure in MLS earlier this term, believing it provides excuses for players not to deliver all year round.

The Swedish superstar has at least followed up those words by guiding LA Galaxy to the playoffs this time, while seemingly on a personal crusade to prove he is the greatest player in league history - sparking a rivalry with Vela.

Galaxy's style of play has not been particularly pretty since trading a potentially smart newly built side for long-ball-to-Zlatan early last year, but it has proved effective on occasion. Notably, LAFC still have not beaten their neighbours in five attempts and might fear another meeting.
 

HAVE NYCFC GOT WHAT IT TAKES WITHOUT BIG NAMES?

New York City made a big bang when they arrived in MLS, signing David Villa, Andrea Pirlo and Frank Lampard, but their star power counted for little in a desperate first season.

Club icon Villa then led NYCFC to the Eastern Conference semi-finals in three straight seasons, before departing at the end of 2018 with the team struggling to recreate the high level of performances under Patrick Vieira with new coach Domenec Torrent.

However, Torrent has got the Bronx outfit playing some of the best football in MLS this season, all without a standout star. The supposedly more modest talents of Anton Tinnerholm, Maxi Moralez, Alexandru Mitrita and Heber, among others, have fired City to the top of the conference, but the playoffs are a different beast.
 

IS THERE LIFE LEFT IN DEFENDING CHAMPS ATLANTA YET?

Despite failing to win the Shield, Atlanta United's class of 2018 might still have a case for being the best team in league history for the timebeing, but they then lost inspirational coach Tata Martino and star playmaker Miguel Almiron after MLS Cup.

Frank de Boer arrived and his infamously unconvincing record outside of Ajax looked set to continue early on, until a string of clean sheets steadied the ship. Even then, it took Martinez's sensational 15-game scoring streak to secure a comfortable playoff spot.

Pity Martinez has not really convinced and a late-season injury for Josef means Atlanta's preparation for their postseason title defence has not entirely gone to plan.
 

THE BEST OF THE REST...

Minnesota United have been a surprise package this year, having added experience last offseason, but a title push is surely beyond them. Rivals Seattle Sounders and Portland Timbers both have experience of success at this time of year, however.

In the East, Wayne Rooney will hope to leave DC United on a high but the signs have not been promising late in the campaign. Philadelphia Union have impressed, while Toronto still have a very strong side on paper.
