5 MLS teams desperate for a win on Matchday 6 this weekend | OneFootball

While MLS mostly played on through the March international match window last weekend, the unwritten rule is that most of the bad results can be forgiven in terms of projecting long-term prospects.

That window is over now, though, and most teams are back to full strength. So as March comes to a close, for several clubs the time is now to make sure their season doesn't go completely off the rails.

With that in mind, here's the five teams that most desperately need a victory on Matchday 6:

New England Revolution

Saturday, 2:30 p.m. ET vs. New York Red Bulls

The Revs still have only one point this season. They still don't have a single player credited with a goal, meaning their leading scorer currently is technically "own goal." They are in a second season under Caleb Porter (top picture) after the first went far worse than expectations. And they're at home against a historic regional rival.

Porter won't be the first manager fired this season because Montreal already parted with Laurent Courtois. But he might be the next if things don't starting going much better, and quickly.

Saturday, 2:30 p.m. ET vs. Vancouver Whitecaps

Robin Fraser took the risky step of reintroducing Lorenzo Insigne to the team last week after he has been personna non grata around the Reds recently. Insigne contributed an assist, but TFC still lost anyway.

If the at times turbulent Italian was still on the outs, there might be more patience with this otherwise rebuilding squad. But returning him to the field amps up the pressure on Fraser and the rest of his charges in a major way.

FC Dallas

Saturday, 8:30 p.m. ET vs. Sporting Kansas City

Signing Luciano Acosta was one of the surprise moves of the offseason, but the results so far have been kind of underwhelming.

That's understandable when you're introducing an MVP-caliber contributor to a new side at the last minute. But there need to be signs of progress soon. And woeful Kansas City, who may be the worst team in the league, is coming to visit. This is the time Dallas and Acosta have to prove the splurge was worth it.

San Diego FC

Saturday, 10:30 p.m. ET vs. LAFC

Yes, Mikey Varas' charges have gotten off to an excellent start to life in MLS in San Diego's expansion season. But their best results so far have come on the road, with SDFC settling for a pair of draws in their first two home matches.

Now they get to welcome one of their new local rivals to town before what should again be close to a packed house, and while the Black-and-Gold may have one eye pointed toward the start of their Concacaf Champions Cup quarterfinal against Lionel Messi and Inter Miami next week. This is an enormous chance for a signature moment.

LA Galaxy

Saturday, 10:30 p.m. ET vs. Orlando City

The Galaxy have gotten up off the mat from their dreadful start with a pair of promising draws over the last two weekends. But now they need to take the next step forward and prove they can still beat a good MLS opponent, at least at home.

The good news is Joseph Paintsil could be back in some form after returning to team training this week, and Christian Ramirez has found his finishing boots with a goal in each of his last two games.
