Jim Curtin knows Philadelphia Union have no margin for error as they chase a playoff spot, with Atlanta United next up for them in MLS.

The Union are currently ninth in the Eastern Conference, having put together big back-to-back wins against New York City FC (5-1) and D.C. United (4-0) in their last two matches.

They have now won three of their last four matches in the league, but Curtin warned his players that they cannot ease off the pressure until their playoff spot is secured.

"Every game is must win now. There's no margin for error for any team that isn't above the red line comfortably," Curtin said.

"The home games always become really critical. We've had a tough schedule, but all these points matter because anything could be the difference.

"There'll be a lot of highs and lows, and everybody still has hope and it's going to be a sprint to the finish. We recognise the challenge, but you have to say must-win until you're mathematically eliminated."

Meanwhile, Atlanta sit two places and three points below their opponents in the table after failing to win any of their last three matches.

They have drawn their last two outings 2-2 though, and interim head coach Rob Valentino is hoping they can take a more direct approach in an attempt to find a cutting edge.

"Do we really think we can play through? Then great, let's do it," Valentino said. "But if I think that we can be more direct and expose their centrebacks or expose a certain area of the pitch, let's go and do it.

"Let's not waste time with the ball. The intentional possession of what we're doing with it. I just want to make sure that we're intentional about what we're doing with the ball."

PLAYERS TO WATCH

Philadelphia Union – Mikael Uhre

Mikael Uhre scored the opening goal in the Union's win over D.C. United on Sunday, his fourth straight match with a goal.

Uhre is the fifth player in Union history to score in four straight regular-season matches, though only one, Daniel Gazdag, has scored in five straight (August-September 2022).

Atlanta United – Edwin Mosquera

Edwin Mosquera's goal at 90+2' for Atlanta United on Saturday was the club's 11th goal from outside the box this season.

Only Sporting Kansas City and Real Salt Lake (12 each) have more in 2024.

MATCH PREDICTION: PHILADELPHIA UNION WIN

The Union have won each of their last four regular-season home matches against Atlanta United. Atlanta's lone win at Subaru Park was a 2-0 victory in July 2018.

The Union have won two straight matches, winning each by a four-goal margin. This is the 15th time in MLS history a team has recorded back-to-back four-goal wins, including the second by the Union (August 2022), but no team has ever won three straight matches by four or more goals.

Meanwhile, Atlanta have won only two of their last 10 regular season matches (D3 L5) dating back to the beginning of July. Each of Atlanta's last two matches ended in 2-2 draws.
