Chelsea looking to history ahead of Camp Nou crusade

MADRID - Since Lionel Messi started playing with Barcelona 15 years ago, few teams have caused as much trouble for the Spanish club as Chelsea.

Barcelona has been dominant with Messi against nearly every opponent it has faced in Europe - but not against Chelsea.

The English club is even used to doing well against Barca at Camp Nou, where the teams will meet on Wednesday in the second leg of their last-16 Champions League tie.
