In the build-up to the eagerly anticipated El Clasico this weekend, Barcelona are struggling to keep their defenders fit.
With Gerard Pique doubtful for their clash with Real Madrid, Carlos Puyol may have to come in to replace the injured defender, having just returned from a long-spell on the sidelines himself.

However instead of spending more money in strengthening their attacking options, the Catalan side should focus on cementing a well established back four.
