Barcelona midfielder Arturo Vidal says they can't get carried away after their 3-0 defeat of Liverpool.

Barca now have a clear advantage after the first leg of their Champions League semi-final tie.

"Without a doubt it was a great result, in the most important game of the year," said Vidal.

"We knew how to suffer, but there are still 90 minutes to go, we have to kill it there," he added.

"We have to respect Liverpool a lot because they are a great team, we're convinced it will be much harder there than tonight."
