Given that these two still harbour slim hopes of an Eastern Conference play-off berth, this is simply must win for both in Foxborough.
Of the two, Atlanta United’s chances are more realistic, kicking off two points and two placed above their hosts.
The Five Stripes enjoyed back-to-back wins, over Toronto and Orlando, but, somehow, could not make that three on the bounce a fortnight ago.
Gonzalo Pineda’s team went close on numerous occasions, but couldn’t find that telling touch, so it finished goalless against Philadelphia Union.
This draw leaves Atlanta ninth in the east, two points below the dotted line, needing to win both of their remaining fixtures to stand any chance.
New England Revolution meanwhile won the Supporters’ Shield little under 12 months ago, setting a new MLS points record.
These days, Bruce Arena’s team are 11th in the east, four points off a post-season spot, with just two games to play.
Last time out, the Revs’ top seven aspirations suffered another setback, beaten 1-0 by Club de Foot Montréal at Gillette Stadium.
So, if New England suffer a fourth successive defeat in this one, their post-season dreams would be over.
Who will claim three priceless points in Massachusetts?
