Major League Soccer is in advanced talks with a Minnesota group seeking an expansion club and will evaluate growing beyond its planned 24 teams, including David Beckham's conditional Miami club.

MLS commissioner Don Garber said Monday that the league, which opened its 20th season 10 days ago with 20 teams, plans to announce a new expansion team by the end of April.

"We remain on track to announce the next MLS expansion market in the next 30-45 days, though no specific date for an announcement has been set," Garber said.

"Over the course of 2015, we plan to evaluate potential expansion beyond 24 clubs."

That decision could help bring development time for the Miami MLS franchise of Beckham, the former England midfielder who starred for Manchester United and Real Madrid and helped the Los Angeles Galaxy win the 2011 and 2012 MLS crowns.

In February of last year, MLS announced it would award an MLS expansion club to Beckham's investment group provided stadium financing and a location could be agreed upon, Garber saying he hoped the team would join Atlanta in taking the field for the 2017 season.

But two stadium sites desired by Beckham's group were rejected by elected officials last July. Officials earlier this month offered Beckham's group a site near the Major League Baseball home ballpark of the Miami Marlins for a new stadium in hopes of making a deal.

If MLS sticks with a 24-team maximum and Beckham's group cannot complete a stadium deal, the conditional nature of the group's expansion team could become an issue with several other cities interested in MLS teams.

In addition to Miami and Atlanta, MLS hopes to welcome Los Angeles FC -- a replacement team for the folded Chivas USA -- in 2017 to boost the league to 23 teams, one less than what had been planned to be the maximum.

Minnesota has the inside track to the 24th team, according to Garber.

"We are in advanced discussions with Bill McGuire and his partners in Minnesota to bring a Major League Soccer expansion club to the Twin Cities and are particularly excited about their plans for a new soccer-specific stadium that will serve as the club's home," Garber said.

MLS is also considering Sacramento in its latest expansion and has talked with hopeful groups in St. Louis and San Antonio.

The renewed talk of adding teams comes as New York City FC, operated by English Premier League side Manchester City and Major League Baseball's New York Yankees, and Orlando City made strong debuts this month.

NYC defeated the New England Revolution 2-0 last Sunday in its Yankee Stadium debut before 43,507 with captain and Spanish great David Villa scoring the first home goal.

Orlando City drew 1-1 with NYC on March 8 before 62,358 spectators at the Citrus Bowl, former Brazil superstar Kaka equalizing with a free kick in second half stoppage time, and beat Houston 1-0 last Friday.
