Question: What two positions were played by the MLS player who went into retirement after winning his 6th MLS crown at the MLS Cup 2014?
Context: The 2014 MLS Cup Playoffs (branded as the 2014 MLS Cup Playoffs presented by AT&T for sponsorship reasons) was the nineteenth post-season tournament culminating the Major League Soccer regular season.  The tournament began in late October and culminated on December 7, 2014 with MLS Cup 2014, the nineteenth league championship for MLS. MLS Cup 2015 was the 20th edition of MLS Cup, the championship game of Major League Soccer (MLS).  The match was to determine the champion of MLS' 2015 season.  The championship was contested on December 6, 2015 between the Columbus Crew SC and the Portland Timbers at MAPFRE Stadium in Columbus, Ohio, with the latter winning 2–1 and earning a berth into the 2016–17 CONCACAF Champions League. The 2015 MLS Cup Playoffs (officially the Audi 2015 MLS Cup Playoffs for sponsorship reasons) was the 20th post-season tournament culminating the Major League Soccer regular season.  The tournament began on October 28 with D.C. United defeating New England Revolution and culminated on December 6, 2015 with MLS Cup 2015, the twentieth league championship match for MLS. The 2010 Major League Soccer season was the 98th season of FIFA-sanctioned soccer, the 32nd with a national first-division league, in the United States and Canada, and the 15th in MLS history.  It began on March 25 at Seattle's Qwest Field with Seattle Sounders FC defeating the expansion Philadelphia Union, 2–0.  The 2010 MLS All-Star Game was played at Reliant Stadium, hosted by the Houston Dynamo on July 28 as the MLS XI fell 5–2 to visiting Manchester United.  The regular season concluded on October 24, with Los Angeles Galaxy winning the Supporters' Shield by one point over Real Salt Lake.  Upon the completion of the regular season the 2010 MLS Cup Playoffs culminated on November 21 with a 2–1 victory by the Colorado Rapids over FC Dallas at Toronto's BMO Field.  It was the first time the MLS Cup final was played outside the United States. Landon Timothy Donovan (born March 4, 1982) is an American former professional soccer player who played as a forward and attacking midfielder.  He holds numerous individual records in Major League Soccer (MLS) and for the United States national team and is often regarded as the greatest American men's soccer player of all-time. MLS Cup 2014 was the 19th edition of MLS Cup, the match that determined the champion of Major League Soccer's 2014 season.  It is also the last MLS Cup to be held before the league's rebranding in 2015.  The Western Conference Champions LA Galaxy played the Eastern Conference Champions New England Revolution.  The match was held at the Galaxy's home field of the StubHub Center in Carson, California, as the Galaxy were awarded home advantage by finishing the regular season with more points than the Revolution.  The Galaxy won 2–1 after Overtime, winning their fifth MLS Cup title and also sending all-time U.S. national team goal scoring leader Landon Donovan into retirement with his sixth MLS Cup crown. The 2007 Carolina Challenge Cup was a four-team round robin pre-season competition hosted by the Charleston Battery.  The Houston Dynamo won the 2007 tournament and went on to win the MLS Cup, marking the fourth consecutive season that the champion went on to win one of the two year-end MLS trophies, the MLS Supporters' Shield or MLS Cup. MLS Cup 2003, the eighth edition of Major League Soccer's championship match, was played between the Chicago Fire and the San Jose Earthquakes to decide the champion of the 2003 season.  The match took place at The Home Depot Center in Carson, California on November 23, 2003.  San Jose defeated Chicago 4–2 with a goal from Richard Mulrooney in the 50th minute.  It was San Jose's second MLS Cup victory in three years.  It was the first MLS Cup in which players from both teams were allowed to wear their primary uniforms.  It was also the first MLS Cup played between two former MLS Cup champions as well as the highest-scoring final, with 6 goals in total. In Major League Soccer, several teams annually compete for secondary rivalry cups that are usually contested by only two teams, with the only exception being the Cascadia Cup, which is contested by three teams.  Each cup or trophy is awarded to the eligible team with the better regular season record and are comparable to minor trophies played for in college football rivalries.  Most cups are deliberately conceived as local derbies between teams in the same region.  Rivalry cups are considered a tradition to most MLS fans and players alike.  Out of the ten original MLS teams only three have not competed in these rivalry cups: Sporting K.C., New England Revolution and the defunct Tampa Bay Mutiny.  Most newer local derbies such as the 401 Derby and Hudson River Derby are not contested for rivalry cups but instead for bragging rights of rival supporters groups.  The only rivalry between two original MLS clubs that do not compete for a cup is the San Jose Earthquakes and the LA Galaxy in the yearly edition of the California Clasico.  The Texas Derby are the only MLS cup rivalry games where the winner does not walk away with a cup trophy.  Instead, the winner takes home "El Capitán" a replica 18th century mountain howitzer cannon. MLS Cup 2008 was the final match of the 2008 Major League Soccer season, and the 13th championship awarded by MLS.  The match took place on Sunday, November 23, 2008, at the Home Depot Center in Carson, California, between the Columbus Crew and New York Red Bulls.  MLS Cup 2008 was the only final in which two Eastern Conference teams met, and the first time since 1996 that both teams made their MLS Cup final debut in the same match.  Columbus won the game by a score of 3–1 with goals from Alejandro Moreno, Chad Marshall, and Frankie Hejduk — all assisted by Guillermo Barros Schelotto.  Schelotto was named man of the match, adding to his MVP award from the regular season.  The Crew became the fourth club to win both MLS Cup and the Supporters' Shield in the same season, following D.C. United (1997, 1999), Sporting Kansas City (2000), and Los Angeles Galaxy (2002).
