And down the stretch they come.

Major League Soccer's regular season will end Sunday afternoon, with all 22 teams playing simultaneously on “Decision Day”. One spot in the MLS Cup playoffs remains up for grabs, and several sides will play to improve their playoff positions.

There's more.

Having already clinched the Supporters' Shield, Toronto vies to set the MLS record for most points in a regular season.

We look at all this and more in our weekly MLS review.

Key talking points

Toronto‘s win over Montreal brought them level with the 1998 Los Angeles Galaxy side for the regular-season points record with 68. Toronto also levelled the 2014 Seattle Sounders side's most regular season wins with 20 and join the 2005 San Jose Earthquakes as the only team to average two points per game. Toronto will visit Atlanta on Sunday, looking to confirm themselves as the greatest regular-season team in MLS history, but the glory they want most will be available on December 9 at MLS Cup 2017.

New York City FC, Chicago Fire, Atlanta United and Columbus Crew all are within three points of second place in the Eastern Conference. They can clinch that spot and the accompanying first-round bye in the playoffs with a win and some help from other games.

San Jose Earthquakes can claim the sixth and final playoff spot in the Western Conference on Sunday when they host Minnesota United. Dallas need to beat LA Galaxy and for San Jose to lose or draw in order to reach the postseason. Real Salt Lake must beat Sporting KC and need Dallas and San Jose need to lose or draw their games to clinch an unlikely playoff spot.

Nemanja Nikolic‘s debut season in MLS has been an unmitigated success. The hat trick the Chicago Fire striker scored on Sunday against the Philadelphia Union earned him the honour of MLS Player of the Week and moved him to the top of the Golden Boot race.

Nikolic's 24 goals is sixth-highest total for a single campaign in MLS history. He trails the single-season goals record by just three and can move into fifth place by scoring once.

MLS Rumours

The Columbus Crew shocked the wider MLS community this week when owner Anthony Precourt threatened to relocate the club to Austin, Texas, if Ohio's capital city doesn't help him build a new downtown stadium. Columbus is one of MLS' charter clubs and has played in Mapfre Stadium, the first purpose-built soccer stadium for a U.S. top-flight team, since 1999. Precourt insists the facility is outdated and limiting the Crew's progress.
