The biggest names in football have been linked to Barcelona and Real Madrid this summer, and many have arrived.Chile forward Alexis Sanchez was unveiled at the Catalan club on Monday, while Jose Mourinho's side are currently on tour with a handful of new recruits, including left-back Fabio Coentrao (who is being used in a more advanced role in the United States), winger Jose Callejon, and midfielders Nuri Sahin and Hamit Altintop. On top of all that, Madrid still hope to bring in a striker, with Neymar, Sergio Aguero, Carlos Tevez and Emmanuel Adebayor all mentioned, while Barca turn their attentions to Arsenal captain Cesc Fabregas.
But what about the defenders?
Barca's backline was notoriously difficult to breach last season as the Catalans conceded just 21 goals in their 38 league games. Nevertheless, coach Pep Guardiola was forced to shuffle his squad in the absence of defensive leader and lynchpin Carles Puyol. Barcelona lost five games in total last season and Puyol was absent in all of those. His presence lifts the players around him and brings the best out of central defensive partner Gerard Pique. Puyol's troublesome knee injury saw him restricted to just seven games after Christmas - a total of just 377 minutes.
