Five different scorers put Barca in charge

BARCELONA - Barcelona took a giant stride towards securing a likely semi-final against arch rivals Real Madrid when they swept to a 5-1 demolition of Shakhtar Donetsk in their Champions League quarter-final first leg on Wednesday.

Andres Iniesta starred for the rampant 2009 winners, three days after becoming a father for the first time, scoring Barca's opener in the second minute at the Nou Camp and creating a second for Daniel Alves just after the half hour.

Gerard Pique added to the home side's tally in the second half and their domination was only briefly checked by a Yaroslav Rakitskiy goal before Seydou Keita and Xavi put Barca almost out of sight ahead of next week's second leg in Ukraine.

A mouthwatering all-Spanish semi-final is a near certainty following Real's 4-0 drubbing of Tottenham Hotspur at the Bernabeu on Tuesday, meaning the La Liga giants would meet an incredible four times in just over two weeks.

They play in the domestic league on April 16 and clash in the final of Spain's King's Cup four days later and would bid for a place in May 28's Champions League final over two legs in the last week of April and the first week of May.

Barca coach Pep Guardiola had warned against underestimating Shakhtar, who recorded a shock 3-2 win at the Nou Camp in December 2008 before Barca went on to win the final and Shakhtar triumphed in the UEFA Cup.

The two teams also met in the final of the European Super Cup in 2009 when a Pedro strike in extra time sealed a 1-0 win for the Spanish side.

"The result is not definitive," Guardiola said in a television interview. "They are a very good team."

"I am more than happy. Looking at our opponent tonight I could not be anything else with a 5-1 victory," he added later.
