The Philadelphia Union have parted ways with head coach Jim Curtin, the club announced on Thursday. 

Curtin was the second-longest serving coach in the MLS, only behind Sporting Kansas City's Peter Vermes, but his 10-year stint at Subaru Park has finally come to an end. 

During the 45-year-old's tenure, the Union won the 2020 Supporters' Shield and made the 2022 MLS Cup final. 

But Philadelphia struggled this season, finishing 12th in the Eastern Conference standings and therefore missing the Audi MLS Cup Playoffs for the first time since 2017.

Curtin oversaw 394 matches in all competitions, winning 170 (D90 L134), ending with a win percentage of 41.9%. 

"We want to extend our heartfelt appreciation to Jim for his passion and dedication to this club over the last 10 seasons," sporting director Ernst Tanner said in a statement.

"He greatly contributed to the success the club has achieved in recent years and for that, we are extremely grateful.

"We thank Jim for the significant impact he made both on the field and in the community. Following the 2024 season, we recognise the need for change.

"We'll continue to evaluate our sporting strategy and make the necessary changes this offseason to best set the team up for success."

In the Western Conference, the San Jose Earthquakes named Bruce Arena as their new head coach and sporting director after a poor 2024 season. 

They conceded an MLS-record 78 goals and finished bottom of the overall league standings, parting ways with Luchi Gonzalez before being led by interim coach Ian Russell.

Arena takes charge of his fifth club in the MLS and his first since resigning from his position with the New England Revolution in 2023. 

The 73-year-old is the most accomplished coach in MLS history, leading the league in regular-season wins (262) and Audi MLS Cup Playoffs victories (35).

Additionally, Arena led the United States at the 2002 and 2006 World Cups and won three CONCACAF Gold Cup titles.

"I am extremely excited for the opportunity to come to San Jose," said Arena.

"I coached my first ever professional game at Spartan Stadium in 1996 – the first game in MLS history – and my first international game with the U.S. in 1998 was in San Jose.

"The Earthquakes and Northern California have a proud soccer tradition.

"There’s a lot of potential with the club, and I am looking forward to working with everyone here to unlock that potential and get back to winning ways."

Bruce Arena is satisfied with New England Revolution's start to the season, though warned the opening four games of a campaign cannot be used to judge how his team will go on to perform.

The Revolution won MLS' Supporters' Shield in 2021 yet struggled last season, finishing 10th in the Eastern Conference.

New England have started this season strongly, however, winning three of their opening four games, albeit their sole defeat came in a 4-0 thrashing at the hands of reigning MLS Cup champions Los Angeles FC.

A 1-0 win over Nashville SC saw New England return to winning ways last week, and though Arena was not entirely happy with the performance, he cannot complain over his team's start to 2023.

"In the last 10 minutes we didn't do a good job defending the lead, we were a bit too negative, but after four games, to have three wins – it's a pretty good start to the season," he told reporters.

"For the most part we've improved this year. We played well [against Nashville]. In the first half we played very well. For 75 minutes it was really good. I didn't like the last 10-15 minutes but overall it was a good performance against a good team."

Arena, though, did bluntly add: "The first four games of the season means absolutely nothing."

Next up for New England are Wayne Rooney's D.C. United, who lost 3-2 at New York City FC last time out.

D.C. United signed midfielder Lewis O'Brien on loan from Nottingham Forest this week, with Rooney saying: "Lewis has been one of the best players in the Championship over the last few seasons.

"He reads the game well and creates goalscoring opportunities. Bringing him in on loan from Nottingham Forest was a great bit of business for us and he will be a brilliant addition to our midfield."

PLAYERS TO WATCH

D.C. United – Christian Benteke

Christian Benteke has netted twice in MLS this season, including D.C. United’s first goal in their loss in New York City. Benteke scored with his only attempt on target, with the striker hitting a further two off target and also creating one chance.

New England Revolution – Gustavo Bou

Bou scored the lone goal in New England's 1-0 win over Nashville on Saturday. He has scored 41 goals in the regular season and play-offs since debuting for New England in mid-2019, 10 more than any other Revs player under Arena.

MATCH PREDICTION – DRAW

With nine points through four matches (W3 L1), the Revolution are off to their second-best start in club history (10 points in 2005).

D.C., meanwhile, are unbeaten in their first two home matches this season, picking up a win over Toronto FC and a draw against Columbus Crew. They have not gone three straight home matches without defeat since a five-match run in August-September 2021 (W4 D1).

New England won the last MLS meeting between the teams, emerging victorious 1-0 at Gillette Stadium last season. Carles Gil scored for the Revs, though the playmaker did not feature against Nashville due to injury.

OPTA WIN PROBABILITY

D.C. United – 34.6 per cent

New England Revolution – 36.7 per cent

Draw – 28.7 per cent

Efrain Alvarez's stunning 77th-minute strike silenced the MLS record crowd of almost 75,000 fans as LA Galaxy got past newcomers Charlotte 1-0 on Saturday.

Expansion side Charlotte drew a single-game attendance record of 74,479 fans, eclipsing the 73,019 mark set by Atlanta United in the 2018 MLS Cup.

Galaxy had the better of the chances with Victor Vazquez hitting the woodwork in the 18th minute, while Javier Hernandez forced a good save from Charlotte goalkeeper Kristijan Kahlina.

Alvarez made the decisive breakthrough with a spectacular left-foot shot from outside the box which nestled into the top corner to spoil the Charlotte party.

Scottish forward Lewis Morgan netted a first-half hat-trick as New York Red Bulls won 4-1 away to Toronto.

Morgan's finishes for his opening two goals were similar, set up by Patryk Klimala with curling right-foot shots in the 17th and 24th minutes.

Jesus Jimenez pulled one back for Toronto, before Klimala released Morgan on halfway and the Scot raced forward to slot home for his treble.

Carles Gil's penalty on the stroke of half-time earned 2021 Supporters' Shield winners New England Revolution a 1-0 home win over Dallas. The victory meant Revs head coach Bruce Arena became the all-time leader among MLS coaches for regular-season wins.

Francisco Calvo scored twice in the final 10 minutes as 10-man San Jose Earthquakes salvaged a 3-3 draw with Columbus Crew.

Ola Kamara netted a stoppage-time winner for DC United as they beat Cincinnati 1-0, while Chicago Fire and Orlando City drew 0-0 and Real Salt Lake won 1-0 over Seattle Sounders.

Colorado Rapids won 3-0 over Atlanta United at home and Vancouver Whitecaps held on for a goalless draw with reigning MLS Cup champions New York City.

Sporting KC got past Houston Dynamo 1-0 while 10-man Philadelphia Union edged Montreal 2-1 and Minnesota United drew 1-1 with Nashville.

Arsenal have a "pretty strong" chance of completing a deal for United States goalkeeper Matt Turner, according to New England Revolution coach and sporting director Bruce Arena.

Turner was voted MLS Goalkeeper of the Year in 2021 after helping the Revs to Supporters' Shield success, though his side fell short in the playoffs with defeat to New York City in the Eastern Conference semi-finals.

The 27-year-old joined the Revs as a free agent in 2016 after going undrafted and has been a regular for the past four seasons, racking up 97 MLS appearances over that time, including 28 last year when recording five clean sheets.

Arsenal have recently been linked with the USA international, who has been capped 13 times by his country, and Revs chief Arena has confirmed talks are ongoing between the two teams.

However, a transfer is not expected to go through this month, with Arsenal instead expected to wait until the end of the Premier League campaign before bringing in Turner – potentially to replace Bernd Leno, the back-up to Aaron Ramsdale.

"As speculated, there's a chance we could lose Matt Turner," Arena told the Sports Hub on 98.5 radio.

"If things work out the right way, we will lose him in the summer. We are in negotiations with Arsenal to complete the transfer. The likelihood of that happening is pretty strong."

Arsenal will reportedly pay an initial £4.5million ($6m) for Turner in a deal that could rise to £7.5m ($10m) with add-ons, which is the same amount Manchester City agreed to pay Columbus Crew for international rival Zack Steffen in 2019.

The delayed move for Turner may now see Leno stay in place for the remainder of the season.

Should he complete a switch, Turner will become the fifth American to sign for Arsenal after Gedion Zelalem, Danny Karbassiyoon, Frank Simek and Doug Farquhar.
