A midfielder (or simply mid) is an association football position. Some midfielders play a more defensive role, while others blur the boundaries between midfielders and forwards. The number of midfielders a team uses during a match may vary, depending on the team's formation and each individual player's role. The group of midfielders in a team is called the midfield.

More complete midfielders require a number of skills on top of fitness: they tackle, dribble, shoot and pass during any match. Most managers field at least one central midfielder with a marked task of breaking up opposition's attacks while the rest are more adept to creating goals or have equal responsibilities between attack and defence. At either side of the pitch a manager can field a right or left midfielder, who are used equally for both attack and defence, or a winger, a player used primarily for attack.

In essence, a good midfield must possess the ability to be combative while also being creative. A good striker without midfield support could lack attacking chances, while a defense likewise could be severely tested. Because they occupy the most influential parts of the pitch, midfielders are perhaps more likely to influence the outcome of a match than other positions, especially if they have vision for a good pass or ability to score.

Sergio Busquets Burgos (Spanish pronunciation: [ˈserxjo βusˈkets], Catalan: [βusˈkɛts]; born 16 July 1988) is a Spanish footballer who plays for FC Barcelona and the Spanish national team, as a defensive midfielder.

He was a relatively obscure player when he arrived in FC Barcelona's first team in July 2008, but eventually made a name for himself in a relatively short period of time, reaching the Spanish national team in less than one year after making his professional club debut.

Busquets was born in Sabadell, Barcelona, Catalonia. In 2005, he joined local FC Barcelona's youth ranks, scoring seven goals in 26 matches for the Juvenil A team in his second season. Two years later, he was promoted to the B team under Josep Guardiola, and helped it achieve promotion to the third division. In that same season he would make his first-team debut, coming on as a substitute in a Catalonia Cup match.

On 13 September 2008, Busquets played his first La Liga match, 90 minutes in a 1–1 home draw against Racing de Santander. During Barcelona's UEFA Champions League match against FC Basel at St. Jakob-Park on 22 October 2008, he scored the second goal in the 15th minute in a 5–0 group stage win. In early December, in another start, he scored his second goal with Barça in the competition, netting in the 83rd minute of a 2–3 home loss against FC Shakhtar Donetsk. On 22 December, Busquets signed a contract extension until 2013, with a buy-out clause of €80 million.

David Robert Joseph Beckham, OBE (born 2 May 1975) is an English association footballer who plays for Los Angeles Galaxy. He has played for Manchester United, Preston North End, Real Madrid, Milan, and the England national team for which he holds the appearance record for an outfield player.

Beckham's career began when he signed a professional contract with Manchester United, making his first-team debut in 1992 aged 17. During his time there, United won the Premier League title six times, the FA Cup twice, and the UEFA Champions League in 1999. He left Manchester United to sign for Real Madrid in 2003, where he remained for four seasons, clinching the La Liga championship in his final season with the club. In January 2007, it was announced that Beckham would leave Real Madrid for the Major League Soccer club Los Angeles Galaxy, signing a five-year contract with them on 1 July 2007. While a Galaxy player, he spent two loan spells in Italy with Milan in 2009 and 2010. On 20 November 2011, he joined an elite group of players to have won three league titles in three different countries, when Los Angeles won their third MLS Cup.

Philipp Lahm (German pronunciation: [ˈfɪlɪp ˈlaːm]; born 11 November 1983 in Munich, Bavaria) is a German footballer who plays for and captains both Bayern Munich and the Germany national football team.

Lahm is considered one of the best full backs in the world, and was included in the World Cup team of the tournament in 2006 and 2010, the UEFA Team of the Tournament in 2008 and in the FIFA Team of the Year 2008. He is well known for his pace, dribbling and precise tackling abilities as well as his small stature. Although Lahm is right-footed, he is able to play on both sides of the pitch. He often cuts from the flank to the inside of the pitch to either shoot or pass.

In August 2011 at age 27 he released his autobiography, Der feine Unterschied: Wie man heute Spitzenfußballer wird (The Subtle Difference - How to Become a Top Footballer), reviewing his football career and personal experiences, the general football environment, football in the social context and the effectiveness of different coaching and training methods. The No.1 bestselling book received extensive media attention in Germany, and has been criticized for parts of the book in which he discerningly analyzed his former coaches work, among the critics were Rudi Völler (himself criticized by Lahm in the book) and Ottmar Hitzfeld.

Arturo Erasmo Vidal Pardo (born 22 May 1987) is a Chilean footballer who plays as defensive midfielder for Juventus and Chile. Although usually deployed as a defensive midfielder, Vidal is a versatile box-to-box midfielder capable of playing in a more attacking role as well.

Vidal was born in San Joaquín, a working class commune in the capital Santiago, the second of six children. His potential was discovered by his uncle and he later joined the youth squads of local Primera División giants Colo-Colo.

Vidal's professional debut came in the first leg of the 2006 Apertura Tournament final. The match was between Colo-Colo and arch rivals Universidad de Chile. Vidal came on as a late substitute for Gonzalo Fierro. Colo-Colo would go on to win the game 2–1 and win the championship as well. In the following season (2006 Clausura Tournament) he became a more important part of the squad and would lead Colo-Colo to their second championship win in a row. Vidal scored three goals in Colo-Colo's Copa Sudamericana 2006 campaign. His good showing caught the eye of scouts from various European clubs.
