Barcelona forward Luis Suarez has insisted that his team only have "a minimal advantage" in their Copa del Rey semi-final against Valencia.

Suarez scored the only goal of the match as Barcelona recorded a 1-0 victory in the first leg of the last-four tie on Thursday night.

The Catalan giants will now visit Valencia for the second leg of the clash next week. Despite the advantage, Suarez is wary of the threat that Valencia will provide at the Mestalla.

"It's a minimal advantage that we have because there are 90 minutes left," Suarez told reporters. "Valencia at home are always stronger and even more so in a Copa semi-final."

Suarez's strike on Thursday night was his third in the Copa del Rey this season, while the striker has managed 16 in 18 La Liga fixtures this term.

The Uruguay international, however, failed to score in any of Barcelona's six Champions League group matches.
