MLS has set the 18-man roster for the July 25 all-star game against European champion Chelsea FC at PPL Park in Chester, Pa.:

Goalkeepers: Jimmy Nielsen*, Kansas City; Dan Kennedy***, Chivas USA.

Defenders: Steven Beitashour*, San Jose; Auerlien Collin*, Kansas City; Jay DeMerit*, Vancouver; Heath Pearce*, New York; Carlos Valdes**, Philadelphia; Ramiro Corrales**, San Jose.

Midfielders: David Beckham*, Los Angeles; Dwayne De Rosario*, D.C. United; Landon Donovan*, Los Angeles; Graham Zusi*, Kansas City; Osvaldo Alonso***, Seattle; Kyle Beckerman***, Real Salt Lake.

Forwards: Chris Wondolowski*, San Jose; Thierry Henry*, New York; Chris Pontius***, D.C. United; Eddie Johnson***, Seattle.

*First XI selection, voted by fans and unveiled last weekend

**Commissioner Don Garber’s picks

***Ben Olsen’s selections

Injuries and scheduling conflicts could force changes over the next week. Keep in mind, unlike all-star games in other sports, tactical decisions came into play as Olsen prepares to confront the Euro champions.

Per the collective bargaining agreement, MLS must name 32 “all-stars” for the purpose of bonuses. The other 14 — who are not part of the preparations or the match itself — will be identified on the day of the match.

Chelsea, which begins its U.S. tour Wednesday at Seattle, announced a 25-player traveling party.
